ZnO nanoparticles have been prepared by a simple method in a short period of time. In this synthetic method, the sample was obtained using Zn(CH3COO)2·2H2O and a new template of hexamine salt. Their crystalline structure and morphology were studied by XRD and SEM. The optical properties of the sample were studied by UV–visible spectroscopy. The absorption spectrum of ZnO shows that the optical band gap is 3.02 eV. In this investigation, the photocatalytic degradation of Indigo carmine(IC) in water was studied. The degradation rate is reduced as a function of increase in the initial concentration of IC. The effects of some parameters such as pH and initial concentration of dye were examined.
