Abstract
A facile ultrasonic horn-assisted reaction has been used to synthesize zinc oxide-reduced graphene oxide (ZnO-RGO) hybrids in dimethylformamide. The incorporation of graphene oxide prevents the cluster formation of ZnO nanoparticles. The photocatalytic performance in degradation of methylene blue has been investigated with ZnO and ZnO-RGO hybrids and the results show that the RGO plays an important role in the enhancement of photocatalytic performance of ZnO-RGO. A direct evidence of electron exchange between ZnO and RGO is confirmed by zeta potentials measurements, which is an established reason for photocatalytic degradation of organic dyes.
