In this study, sol–gel method was employed for the synthesis of nanosized ZnO. The phase structure and morphology of the synthesized ZnO was characterized by XRD, SEM and TEM. The FT-IR spectra, room temperature photoluminescence (PL) spectra, diffuse reflectance spectra (DRS), and BET surface area were also examined. Then the efficacy of the synthesized zinc oxide nanoparticles was evaluated as a catalyst for the photodegradation of RhB dye (unhydrolysed and hydrolysed form) and its simulated dyebath effluent. Thereafter the photocatalytic activity of the synthesized ZnO particles was compared with that of commercial ZnO. Experiments performed to investigate the reusability of the prepared ZnO showed that it could be used effectively upto four cycles.
