Solvothermal Synthesis and Visible Photocatalytic Activity of Zn0.4Cd0.6S/TiO2 /Reduced graphene oxide Nanocomposite

ShiYongji, SunBotao, WangXinwei, GuoDeshuang


Zn0.4Cd0.6S/TiO2 /Reduced graphene oxide (Zn0.4Cd0.6S/TiO2 /RGO) nano-photocatalyst was synthe-sized by a facile solvothermal method. During the reaction, TiO2 and Zn0.8Cd0.2S nanoparticles were evenly dispersed across the surface of RGO, which enhanced response to visible light. The photocatalytic activity of as-synthesized Zn0.4Cd0.6S/TiO2 /RGO nanocomposite was studied by means of degrading methylene blue (MB) through the irradiation of visible light. Compared with other nanocomposites, the Zn0.4Cd0.6S/TiO2 /RGO nanocomposite showed the highest photocatalytic degradation efficiency (96%) and high stability, which was 5.4 times of photodegradation efficiency of pure TiO2.
