Preparation and corrosion resistance of ZnO/GO composite thin film electrodes
In this paper,ZnO/graphene oxide(GO)composite thin film materials were prepared by sol-gel method.It was found by scanning electron microscopy that there was no obvious gap between the GO particles in the composite film,and the density was good.The successful doping of GO in the ZnO film was confirmed by Fourier infrared spectroscopy test.By anodic polarization test,it was found that the corrosion potential value of ZnO/GO composite film was positively shifted and the value of corrosion current density was decreased compared with ZnO film.The AC impedance test indicated that the corrosion resistance of the composite films was improved by doping of GO.The best corrosion resistance was obtained for the film samples annealed at 450 ℃.Linear scanning voltammetry curves showed that the current density of ZnO/GO composite films was higher than that of ZnO films,indicating that the electrocatalytic activity of the film material was improved by composite of ZnO particles.
