Synthesis and Characterization of ZnO/NiO and Its Photocatalytic Activity

Bimetallic ZnO/NiO was synthesized by a simple one-pot solvothermal method with zinc nitrate hexahydrate and nickel nitrate hexahydrate in ethanol medium. Material was characterized by X-ray diffraction, Field emission scanning electron microscope, UV-Vis and FTIR. The proposed mixed oxide was investigated as a suitable photocatalytic material for the degradation of organic dyes under visible light irradiation. The formation of ZnO/NiO hetero-junction improved the separation rate of photogenerated electrons and holes and therefore yields enhanced photocatalytic efficiency.
