CdS Nanoparticle-Modified α-Fe₂O₃/TiO₂ Nanorod Array Photoanode for Efficient Photoelectrochemical Water Oxidation.

ABSTRACT: In this work, we demonstrate a facile successive ionic layer adsorption and reaction process accompanied by hydrothermal method to synthesize CdS nanoparticle-modified α-Fe₂O₃/TiO₂ nanorod array for efficient photoelectrochemical (PEC) water oxidation. By integrating CdS/α-Fe₂O₃/TiO₂ ternary system, light absorption ability of the photoanode can be effectively improved with an obviously broadened optical-response to visible light region, greatly facilitates the separation of photogenerated carriers, giving rise to the enhancement of PEC water oxidation performance. Importantly, for the designed abnormal type-II heterostructure between Fe₂O₃/TiO₂, the conduction band position of Fe₂
