Achieving Highly Efficient Photoelectrochemical Water Oxidation with a TiCl₄ Treated 3D Antimony-Doped SnO₂ Macropore/Branched α-Fe₂O₃ Nanorod Heterojunction Photoanode.

ABSTRACT: Utilizing photoelectrochemical (PEC) cells to directly collecting solar energy into chemical fuels (e.g., H₂ via water splitting) is a promising way to tackle the energy challenge. α-Fe₂O₃ has emerged as a desirable photoanode material in a PEC cell due to its wide spectrum absorption range, chemical stability, and earth abundant component. However, the short excited state lifetime, poor minority charge carrier mobility, and long light penetration depth hamper its application. Recently, the elegantly designed hierarchical macroporous composite nanomaterial has emerged as a strong candidate for photoelectrical applications. Here, a novel 3D antimony-doped SnO₂ (ATO) macroporous structure is demonstrated as a transparent conducting scaffold to load
