The research on photocatalytic semiconductor materials

\nA requirement for energy availability and environmental pollution control represents two critical challenges that necessitate immediate resolution. Among the multitude of alternative energy sources, solar green energy emerges as a distinct leader. Semiconductor materials are widely used in many fields of photocatalysis. Contaminant degradation and energy conversion using photoresponsive semiconductor materials. Furthermore, the creation of efficient photocatalysts is of paramount importance. In this paper, the basic principle of photocatalytic semiconductor and the whole process of photocatalytic reaction are introduced in detail. The process of photocatalytic reaction basically includes three stages, and the modification of photocatalytic semiconductor materials are also reviewed. In order to give full play to the excellent properties of semiconductor materials, optimizing the synthesis technology according to the different distribution of doping concentration is the main aspect of future research. It has been extensive used as a treatment of organic pollutants, photocatalytic water splitting and carbon dioxide reduction.\n
