Light absorption enhanced spherical CuS submicron material and preparation method thereof

The invention discloses a light absorption enhanced spherical CuS submicron material and a preparation method thereof. The preparation method comprises the following steps: adding copper sulfate and sodium thiosulfate into deionized water, then fully stirring, meanwhile, adding polyvinylpyrrolidone (PVP), continuously stirring until polyvinylpyrrolidone and PVP are completely dissolved, transferring the fully dissolved mixed solution into a reaction kettle with a polytetrafluoroethylene lining, placing the reaction kettle in a constant-temperature environment of 120-160 DEG C, carrying out a heating reaction for 8-12 h, washing and centrifuging the obtained reaction product, and drying the obtained black brown precipitate to obtain the spherical CuS submicron material with enhanced light absorption. The method is easy to operate and suitable for industrial production, and the obtained spherical CuS submicron material is high in crystallinity, large in specific surface area and good insunlight absorption perfo
