Abstract: Because the nanostructure semiconductor metal sulfide has the unique physical and chemical properties, making it apply in photoelectric material. Therefore, according to the latest research progress at home and abroad, this paper has a detailed introduces of the factors affecting copper sulfide nanostructures, such as material, solvent, reaction temperature, reaction time. At the same time, we introduced band gap of the different morphology and the research progress of degradation of organic pollutants. Also we introduced the research progress of composite materials photocatalytic degradation of organic matter. Finally, in order to make some achievements on this field has certain help, the affecting factors of the band gap and application prospect of CuS were discussed.
