Abstract
NiO/ZnO nanocomposites synthesized by sol-gel method with zinc chloride and nickel nitrate hexahydrate in ethanol used as solvent. Material was characterized by Particle size analyzer, UV-Vis, FTIR, TGA and DSC. NiO/ZnO nanoparticles investigated as a suitable photocatalytic material for the methylene blue degradation i.e. an organic dye under visible light irradiation. The UV–vis absorption spectra of the NiO/ZnO nanoparticles shown peaks in the UV region, corresponding to the band gap of the NiO/ZnO nanoparticles. The band gap of NiO/ZnO nanoparticles is calculated 3.55 eV by Tauc’s plot method. Then UV visible data showed the methylene blue degradation with NiO/ZnO nanoparticles, behaving as active catalyst.
