Description

technical field [0001] The present invention relates to a preparation method of a compound, in particular to a preparation method and application of copper-zinc-tin-sulfur. Background technique [0002] Photocatalyst is a reagent that can use light energy to carry out photocatalytic reactions. Its application fields include: surface self-treatment, degradation of pollutants in the environment, etc. The common photocatalyst is titanium dioxide photocatalyst, because of its wide band gap, its application is limited to the range of ultraviolet light. [0003] In recent years, researchers have devoted a lot of energy to exploring photocatalysts with good photocatalytic response in the visible light range, so as to make full use of natural sunlight energy to improve the efficiency of photocatalysts. [0004] However, the cost of existing photocatalysts is too high; many cannot be catalyzed under natural light, which requires other operations during use, which is very inconvenien...
