摘要：
We report a photoanode based on Fe2O3/zinc oxide (ZnO) heterojunction synthesized by hydrothermal method for photoelectrochemical (PEC) water splitting. The forming heterojunction is systemically characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results from the I-V characteristic curve and conversation efficiency of Fe2O3/ZnO heterojunction reveal that the forming heterojunction would be a benefit for electron transferring from conduction band of ZnO to that of Fe2O3. However, the quantity of ZnO film has an effect on the photocurrent density, the suitable of which has shown enhanced PEC performance.
