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

ShiYongji, SunBotao, WangXinwei, GuoDeshuang

Abstract


Zn0.4Cd0.6S/TiO2/Reduced graphene oxide (Zn0.4Cd0.6S/TiO2/RGO) nano-photocatalyst was synthesized 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 nanomaterial was studied by means of degrading methylene blue (MB) through the irradiation of visible light. Compared with other nanomaterials, the Zn0.4Cd0.6S/TiO2/ RGO nanomaterials showed the highest photocatalytic degradation efficiency (96%) and high stability, which was 5.4 times of photodegradation efficiency of pure TiO2.
