Abstract. As a representative intrinsic type P inorganic semiconductor material, copper (I) oxide Cu2O has been widely used in photovoltaic, catalysis, chemical industries and other fields, and has an extremely important position. For a long time, the literature on the preparation method and preparation technology of Cu2O is relatively scattered and independent, resulting in a certain degree of obstacles and difficulty in obtaining relevant technical knowledge and understanding its internal principles. Aiming at the progress and innovation of Cu2O preparation methods and technology in recent years, combined with the team's long-term experience accumulation and research results, this article focuses on the classification, principles and characteristics of Cu2O preparation methods, and the optimization methods and development directions of Cu2O preparation technology. The outlook was carried out. This review aims to provide reference and guidance for the preparation and research of Cu2O and other related inorganic oxide semiconductors.

In nature, most inorganic oxide semiconductor materials show intrinsic n-type semiconductor properties, such as n-TiO2, n-ZnO, n-wo3 and n-fe2o3 [1-4]. There are oxygen ion vacancies in their crystal structures, which contain free moving electrons. In contrast, a few inorganic oxides represented by cuprous oxide (Cu2O) have metal ion (copper ion) vacancies, which show the intrinsic p-type semiconductor characteristics, namely hole transport characteristics. Due to the increasingly prominent importance of p-type oxide semiconductors in the fields of energy and materials, and the number of p-type oxides that can be selected is very rare compared with that of n-type oxides, Cu2O, as a representative p-type oxide among them, has attracted much attention in many research fields [57]. Human beings are not unfamiliar with Cu2O. As early as 1926, Cu2O was applied to rectifier diodes [8]. In 1930, Schottky put forward the theory of "photovoltaic effect" based on Cu2O barrier [9]. In modern times, Cu2O has been widely involved in the fields of photovoltaic and photocatalysis and has become a "guest" of light energy conversion materials.
As a traditional inorganic oxide semiconductor material with a long history, the previous literature has introduced and summarized the preparation methods of Cu2O to a certain extent, but the content is relatively scattered and independent, and the explanation of the process and mechanism is relatively brief. This research group has been studying the synthesis, preparation and research of Cu2O materials for more than ten years. This paper will systematically classify, summarize and summarize a wide variety of Cu2O preparation methods, and deeply analyze various technical schemes, in order to enlighten and help the related research of Cu2O.

Thermooxidationmethod is the simplest Cu2O synthesis method. As the name suggests, this method takes copper as raw material and oxidizes copper in an aerobic environment, in order to convert copper into Cu2O in one step, as shown in Formula 1. However, because it is difficult to accurately control the oxidation degree of copper, it is usually accompanied by the formation of copper oxide (CuO) (formula 2). A. O. Musa et al. [10] analyzed and studied the oxidation process and products of copper in air atmosphere. It was found that below 1040 X, the oxidation product of

copper was a mixture of CuO and CU2O. The emergence of CuO could be avoided as much as possible only when the oxidation temperature was controlled above 1050 °c. 10. Hong et al. [11] reported that copper nanowires synthesized by polyvinyl pyrrolidone (PVP) template method can be spontaneously oxidized to Cu2O nanowires at room temperature, with a diameter of about 10nm. However, this method is not suitable for other copper substrates, so it is difficult to popularize. It is not difficult to see that although the thermal oxidation method has low requirements for equipment, simple steps and high output, the one-step oxidation of copper to Cu2O in air atmosphere is still a relatively extensive chemical process. It is not only easy to generate Cu2O in the heating and cooling stages, but also the subsequent process often requires pickling and etching to obtain relatively pure Cu2O.

In order to avoid the complex reaction path of copper in the thermal oxidation method, our research group developed the thermal reduction method to complete the preparation of high-purity Cu2O [12]. Unlike the thermal oxidation method, which uses copper as raw material, the thermal reduction method uses CuO as raw material and uses the reducibility of metal copper to reduce CuO to Cu2O, that is, at high temperature, copper is used to reduce CuO and react to produce Cu2O (formula 3). In the specific operation, our research group first takes the metal copper as the substrate, calcines the surface layer of the copper substrate under the air atmosphere to produce CuO with a certain thickness, and then anneals at high temperature in an inert atmosphere (such as argon and nitrogen). At this time, the inner copper atom gradually reduces the surface layer CuO to Cu2O. When the annealing temperature reaches more than 700 °c, CuO is fully reduced to obtain a high-purity Cu2O film (Figure 2). In other embodiments, Luo et al. [13] first oxidized the surface of the copper substrate to form copper hydroxide (Cu (OH) 2) nanowires by electrochemical oxidation, and then transformed the copper hydroxide nanowires into Cu2O nanowires by thermal reduction reaction in an inert atmosphere (Figure 3).

Chemical vapor deposition (CVD) is a process in which the substrate is exposed to one or several precursor atmospheres, and the precursor reacts on the surface of the substrate to produce the target product. H. Kobayashi et al. [14] used chemical vapor deposition to supply the precursor Cui to the reactor growth zone at 883k with cuprous iodide (Cui) as the precursor and N2 as the carrier gas. Finally, Cu2O thin films with a band gap of 2.38ev and high crystallinity were grown on single crystal mgo {110} substrates. H. Kim et al. [15] reported that the hall mobility of Cu2O thin films prepared by atomic layer deposition using a fluorine-free amino alkoxide precursor can reach 8.05cm2v-1s-1. Atomic force microscopy (AFM) was used to analyze the roughness of Cu2O films deposited by atomic layers at different growth temperatures. The results showed that the roughness of Cu2O films increased with the increase of temperature (Figure 4).

Magnetron sputtering technology is the most widely used vacuum coating technology in industry at present. It has significant technical advantages and can be used for the preparation of all thin film materials; Moreover, the prepared film material has high density, few pinholes and good repeatability. The chemical composition of the film can be adjusted by adjusting the composition of the target material. When preparing Cu2O thin films by magnetron sputtering, there are many solutions. Reactive sputtering can be carried out with copper as the target and oxygen as the reaction gas (Formula 1) [16]. Or use CuO ceramic target for reactive sputtering; Cu2O target can also be directly used for direct sputtering. Y. S. Lee et al. [17] prepared Cu2O semiconductor films by reactive

DC magnetron sputtering on quartz substrates with metal copper targets and used the method of controlling the substrate temperature and changing the reaction atmosphere flow rate ratio (AR : O2) to regulate the grain size and phase purity of Cu2O films. The results showed that the grain size gradually increased with the increase of substrate temperature (Figure 5). Similarly, K. K. Markose et al. [18] prepared Cu2O thin films on the surface of monocrystalline silicon by RF magnetron sputtering with copper as the target, oxygen as the reaction gas and argon as the sputtering gas. S. Noda [19] directly used sintered Cu2O and CuO ceramic targets to prepare Cu2O films by adjusting the flow rate ratio of oxygen and argon during magnetron sputtering and controlled the crystalline phase of the films. After high temperature annealing, the hall mobility of Cu2O films was 16.6cm2v-1s-1, and the carrier concentration was 3.5 x 1015cm-3

Pulsed laser deposition (PLD) is widely used in laboratory research at present. It also benefits from its wide range of materials, easy adjustment of target element components, and high film forming quality. In 2003, m. ivill et al. [20] used pulsed laser deposition technology (Mn doped Cu2O target, KrF excimer laser, 5Hz laser frequency, laser pulse energy density of 1~3jVcm2) to prepare Mn doped Cu2O thin films with high conductivity on single crystal MgO substrate. S. Lee [21] using KrF excimer laser (X= 248nm) and CuO ceramic targets. By changing the absorbed atomic energy and flux of laser pulses, it was found that Cu2O nanostructures with different crystal plane orientations and geometric shapes could be grown on the surface of strontium titanate (SrTiO3, STO) substrates with different orientations (Figure 7). In 2009, chen [22] prepared Cu2O polycrystalline thin films on si {100} substrates by pulsed laser deposition. The results show that with the increase of oxygen partial pressure, the structure of the film gradually changes from Cu2O to CuO (the critical value of oxygen partial pressure is 0.4pa) (Figure 6). 10. H. Liu et al. [23] reported the technology of depositing single crystal Cu2O thin films on mgo {110} substrates by pulsed laser deposition, and studied the effect of deposition oxygen partial pressure on the structure and properties of the films. The results showed that pure Cu2O with high crystallinity and high transmittance was prepared when the oxygen partial pressure was 0.09pa. The single crystal Cu2O films deposited under the optimum conditions showed excellent carrier mobility (23.75cm2v-1s-1) and carrier concentration (3.94 x 1016cm-3) and extremely low resistivity (6.67 Q cm).

Hydrothermal method generally uses water as solvent to grow crystals under high temperature and high pressure in a closed pressure vessel. If water is replaced by organic solvent, it is called solvothermal method. 50. F. Guo et al. [24] first reported the hydrothermal synthesis of Cu20 nano cubes with hollow cubic structure. Through hydrothermal synthesis, our research group also realized the growth of Cu20 single crystals that simultaneously exposed three crystal planes {100}, {110}, and {111} (Figure 8), and systematically studied the physical and chemical characteristics of each crystal plane of Cu20 single crystal. The experiment found that the deactivation of Cu20 single crystal was not a one-step deactivation previously inferred, but a two-step deactivation process of oxidation before reduction, which provided a theoretical basis for the study of photocatalysis of single crystal Cu20 [25].
Solvent reduction method is the most used method to prepare Cu20 powder materials. It has the advantages of low cost, simple process and high purity. This method generally uses soluble divalent copper salts (such as CuCh, CuS04, Cu (N03) 2, etc.) as raw materials to react with reducing agents to reduce divalent copper to monovalent copper. Common reducing agents include hydroxylamine, hydrazine hydrate, formaldehyde, etc. In the chemical experiment class in high

school,we experienced the process of glucose reducing copper hydroxide to produce Cu2O. Similarly, M. Z. Wei et al. [26] dissolved CuSO4 5H2O and NaOH in deionized water and stirred them until they were fully mixed. At the same time, ethanol was added as reducing agent and solvent. After heat treatment at 140 °C, Cu2O nanorods with different aspect ratios were successfully prepared. C. S. Tan et al. [27] dissolved cu2+ in aqueous solution containing surfactant and used hydroxylamine and glucose as reductants to prepare Cu2O single crystal particles with specific morphology.

Hydrolysismethod is a method that takes univalent copper compounds (such as CuCl, CuAc, cu2so4, etc.) as reactants to obtain CU2O through hydrolysis reaction. H. Liu et al. [28] used hydrolysis method according to the characteristics of different reactions of CuCl in water with different pH values (i. e. complexing at low pH values (pH<2.4) and disproportionation (2.4<pH<5.0), alkaline hydrolysis reaction occurs when ph>5.0), and uniform hollow CU2O nano cubes are prepared (Figure 9). Other reactants include sodium sulfite, sodium phosphate, etc. after the reaction, the suspension of CU2O is obtained, and then the product is obtained by centrifugation and drying. This method is only applicable to powder materials, and the obtained CU2O has uniform grain size and high yield.

In addition, the research group used the two-electrode method to study the electrochemical deposition of Cu2O. It was found that when the voltage was controlled in the appropriate range (1.0~1.5v), high-quality Cu2O single crystal films could be grown in situ by electrochemical deposition. The SEM image shown in Figure 12a-g shows the growth process of single crystal thin film. From the Figure, we can observe that in the initial stage (0-5min), the regular top up Cu2O nano cube is highly dispersed on the substrate, and its grain size increases with the extension of deposition time. After electrochemical deposition for 10 minutes, the size of the nano cube increased to about 300nm, and most of the nano cubes were interspersed with each other. At the same time, a layer-by-layer growth mode was observed. Finally, the grown nano cubes were combined to form a dense single crystal film, and many triangular pyramid structures were displayed on the surface. Each triangular pyramid exposed three {100} crystal planes, as shown in the simulated three-dimensional crystal structure diagram (Figure 12h) [37]. High-quality electrochemical growth can also regulate the exposed crystal surface, and then obtain Cu2O single crystal films with different crystal exposed surfaces on both sides (Figure 13 a)
Figure 12. (a-g) SEM images of the growth process of the Cu2O single crystal film over time; (h) Schematic plot of the orientated growth of the Cu2O single crystal film along the z-axis [37]
The surface of Cu2O single crystal films grown under strong alkaline conditions is covered by {100} crystal planes, and the back is composed of {111} crystal planes. From the cross-sectional SEM photos (Figure 13b), it can be observed that the Cu2O single crystal film obtained by this technology is uniform and dense inside, showing the characteristics of less grain boundaries and fewer defects. At the same time, this Cu2O single crystal film with crystal plane anisotropy grown by electrochemical deposition has the characteristics of carrier self separation compared with the Cu2O single crystal film with crystal plane anisotropy, and has the potential to use both thermal energy and light energy (Fig. 13c-d). In the subsequent research, according to the mechanism of Cu2O single crystal film (deactivation results from the contact between Cu2O and protons), our research group proposed that the selection of protective layer must be dense to isolate protons on the one hand, and conducive to electron conduction to complete carrier transport on the other hand. Therefore, in the follow-up study, the Ag film (10nm) deposited by polyurethane acrylate (PUA) and high-power pulsed magnetron sputtering (hipims) were used to form a dense proton isolation layer, which inhibited the deactivation of Cu2O single crystal film [35, 36].

The preparation methods of Cu2O continue to develop and mature, which can be divided into solid-phase synthesis, gas-phase synthesis and liquid-phase synthesis. Thin film and monocrystallization of Cu2O are the most obvious development trends. Thin film means that Cu2O can be standardized and prepared in large size. Single crystal can make the internal crystals of the film perfectly arranged and reduce grain boundaries and crystal defects. Exploring the preparation technology with high film forming quality and controllable exposure of crystal surface will become the research focus of Cu2O preparation technology. In addition, the research and development of Cu2O also has the trend of functionalization and low cost. For example, the development of Cu2O single crystal films with high hole transmission performance by low-cost electrochemical deposition has great application potential in the field of heterojunction photovoltaic devices.
To sum up, it is believed that with the continuous efforts of scientific researchers and the continuous exploration of growth mechanism and synthesis methods, the corresponding new efficient and stable Cu2O will become a semiconductor material with good performance and wide application, and will eventually be put into practical application, serving the fields of photocatalytic decomposition of water to produce hydrogen, reduction of carbon dioxide, hole transport materials for solar cells, biosensors, catalytic degradation, semiconductor functional devices and so on, Make great contributions to the progress of human society.
