Abstract
Metal oxide semiconductor materials onto g-C3N4 and rGO as photocatalysts have attracted considerably due to its potential application in different fields, special in environmental treatment. In this paper, we report the synthesís of ZnO/g-C3N4/rGO through hydrothermal method from ZnO/g-C3N4 and rGO. The effect of ratio of the ZnO và g-C3N4 on the structural and morphology of the synthesized nanoparticles were perfomed. The obtained results from characterization methods such as XRD, SEM, FT-IR, EDX,… showed that the materials have a high crystallinity, and ZnO particles were dispersed highly onto g-C3N4 sheets as well as layers of graphene oxide reduced. The photocatalytic activity of ZnO/g-C3N4/rGO was estimated through the degradation of Ciprofloxacin (CIP) in aqueous solution. CIP decomposition efficiency is up to 90% after 240 minutes exposuring to sun light irradiation.
