石墨烯氧化物薄膜电极的光电化学特性
Photoelectrochemical Properties of Graphene Oxide Thin Film Electrodes
摘要
Abstract
A series of graphene oxide (GO) thin films were prepared by a dip-coating method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, ultraviolet-visible (UV-Vis) light absorption, and photoelectrochemical measurements.A cathodic photocurrent was observed for the GO electrodes and the photocurrent density was influenced by the thickness of the films. The GO film electrode with an average thickness of 27 nm gave a by UV irradiation and the cathodic photocurrent decreased gradually with UV irradiation time. This work provides a simple method to change the photoelectrochemical property of GO films by controlling the film thickness or UV irradiation time.关键词
