Herein, we report the facile synthesis of In₂O₃@In₂S₃ core-shell nanocubes and their improved photoelectrochemical property. In₂O₃@In₂S₃ core-shell nanocubes are grown on a F-doped SnO₂ (FTO) glass substrate by a two-step process, which involves the electrodeposition of In₂O₃ nanocubes and a subsequent ion-exchange treatment. The improved light-harvesting ability and the suitable band alignment of the In₂O₃@In₂S₃ core-shell nanocubes generate a remarkable photocurrent density of 6.19聽mA聽cm^鈭? (at 0聽V vs. Ag/AgCl), which is substantially higher than the pristine In₂O₃ nanocubes. These results provide a new insight into the design of a high-performance photoanode for photoelectrochemical water splitting.
