Synthesis and Photo-Catalytic Performance of ZnO/Graphene Composites

Abstract:

Zinc acetate dehydrate and Graphene oxide (GO) were employed as raw materials, the ZnO/Graphene composites were simply and quickly synthesized by solvothermal reaction at 180°C for 12 h. The phase structure and morphologies of the as-obtained composites were characterized and observed by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). Using RhB solution simulated dye wastewater, the composites’ photo-catalytic performance were preliminary tested and observed with the visible light irradiation. The results indicated that the concentrations of zinc acetate and the mass ratio of zinc acetate dihydratio and graphene oxide all had an impact on the photo-degradation rate. The photo-degradation rate of the composites prepared with the concentrations of zinc acetate of 0.01 mol/L was higher than that of zinc acetate of 0.001 mol/L. The mass ratio of zinc acetate dehydratio and graphene oxide of 4:1 was higher than that of 8:1.
