Water scarcity is currently found to be a major issue in many parts of the planet Earth, and it is becoming worse every day as a result of environmental pollution, industrial expansion, changing climatic patterns, and a significant global population growth. The consumption of non-potable water carries health risks due to the presence of contaminants and pathogens, especially affecting vulnerable populations and contributing to the spread of diseases. Desalination processes are trustworthy methods that can handle the increasing need for clean water. Solar energy has long been seen as a pure, limitless source of energy, which has prompted studies on solar energy applications for the production of solar steam, and water desalination. However, balancing the solar energy produced with operational and manufacturing costs presents a hurdle for scientific and commercial applications. Interfacial solar steam generation (SSG) is emerging as a scalable and economically viable solution to the worldwide issues of water pollution and scarcity. Photothermal materials (PTMs) developments have also been the primary cause of the growing interest in SSG for water filtration in the past few years. The application of gold nanoparticles for the purpose of seawater desalination is investigated. The efficiency of gold nanoparticles under the action of solar radiation from the water surface, from the bottom and from the water volume is shown.
