Immobilization of rGO/ZnO hybrid composites on the Zn substrate for enhanced photocatalytic activity and corrosion stability

In this study, a plasma electrolytic oxidation (PEO) process was used to the immobilization of the reduced graphene oxide (rGO)/zinc oxide (ZnO) hybrid on the zinc substrate. The microstructural and compositional characteristics confirmed the successful formation of the rGO/ZnO hybrid composite coatings immobilized on the zinc substrate with crater-like surface morphology. By increasing the content of rGO nanosheets incorporation, the average...
