Photoelectrochemical water splitting over transition metal oxide photoanodes has attracted increasing attention as environmentally friendly and cost-effective method to produce hydrogen. In this work, we demonstrate that hydrogenation and nickel hydroxide coating can significantly improve the photoelectrochemical properties of ZnO nanorod photoanode. The nickel hydroxide decorated hydrogenated ZnO (Ni(OH)(2)/H-ZnO) nanorods exhibit substantially higher photoelectrochemical performance than the pristine ZnO and H-ZnO nanorods, which achieve a remarkable photocurrent density of similar to 910 mu A cm(-2) at 0.4V (vs. Ag/AgCl) under white light irradiation. Moreover, the Ni(OH)(2)/H-ZnO nanorods has a good stability without any photocurrent decay after 3 h irradiation.
