Photon heating opens up new opportunities for science and technology, offering innovative solutions for medicine and materials science. For example, photon heating using MXene nanoparticles to generate solar steam is a pioneering area of research that opens up new possibilities in the field of alternative energy. This process uses light to heat MXene nanoparticles in water, resulting in the generation of steam. MXene nanoparticles, known for their unique electronic and optical properties, can be optimized to enhance the photocatalytic process [1]. This allows accelerating the photocatalysis process and enhancing the photoresponse. The application of this method can be particularly useful in the field of solar energy, where efficient conversion of sunlight into energy is key. In addition, this process can be used to produce valuable chemicals or purify water [2]. This makes it potentially revolutionary in the field of alternative energy and sustainable development. This work demonstrates a simple and effective strategy to develop a composite membrane for efficient photothermal desalination based on MAX phase Ti2AlC:Y (Y 0.2 wt.%) nanoparticles (fig.1). The solar energy-to-water vapor conversion efficiency of Ti2AlC:Y (Y 0.2 wt.%) nanoparticles of MAX phase Ti2AlC:Y is significantly superior to that for MXene Ti3C2Tx nanoflakes and any other MXene nanoflakes.
