Synthesis and Visible-light Photocatalysis of MoS_2/TiO_2 Compound Materials

MoS2/TiO2 nanomaterial prepared by sol-gel process was characterized by XRD,UV-VIS-DRS,BET and so on.Meanwhile methylene blue(MB) was taken as the probe molecular to evaluate the visible light photocatalytic activity of the compound semiconductor materials.The effects of ration of MoS2 in composite catalyst,the initial concentration of methylene blue and the quantity of catalyst on the degradation rate of the methylene blue solution were investigated.The results show that the compound semiconductor materials exhibited the best photocatalytic activity being the decolorization proportion of methylene blue is 96.5% when the quantity of catalyst 0.5 g·L-1,the initial concentration of methylene blue is 0.284 mmol·L-1 under visible light.
