摘要：
A one-step high-temperature hydrated-sulfate assisted solvothermal method has been developed to synthesize TiO2/sulfide nanocomposite spheres. Different hybrid spheres of TiO2/CdS, TiO2/Cu2S, TiO2/FeS, TiO2/Co9S8, and TiO2/ZnS were readily prepared by exploiting different hydrated sulfate. The hydrated sulfate has been proved to play multifunctional roles during the synthetic process, such as spherical template, water supplier, and composition controller. Nanocrystal CdS can be reduced from CdSO4 at a high solvothermal temperature of 350 degrees C, and the TiO2/CdS nanocomposite spheres prepared by this method exhibit superior visible-light-driven photocatalytic efficiency because of its effective heterointerface and high crystallinity.
