Abstract
A simple and a very convenient solution combustion method have been described to obtain ZnO nanoparticle. The band gap energy, particle size and morphology were studied by absorption spectra, XRD and SEM. The photocatalytic activity of synthesized ZnO nano particle on Brilliant red dye was studied by varying pH, amount of catalyst and dye concentration respectively. According to the XRD the average crystallite size of ZnO was found to be 41nm and the band gap energy of ZnO was found to be 3.2 eV. The photocatalytic degradation efficiency of this nanoparticle was found to be 100%, 98.6%, and 87.3% for 25, 50 at 75 mg/L dye concentrations respectively against Brilliant Red dye.
