Abstract: Acquiring solar fuels is considered as one of the most basic strategies to solve the challenges of energy shortage and environment pollution. Photocatalysis is a very promising technology to convert solar energy into chemical energy by splitting water for hydrogen, and reducing carbon dioxide for methane, methanol etc. The central task in realizing the practical application of photocatalysis is to develop sufficiently efficient photocatalysts. The characteristics of surface atomic structure and electronic structure in semiconductor photocatalysts intrinsically determine the absorption range, absorbance, and redox power of photoexcited electrons and holes as well as their bulk diffusion and surface separation capability, which consequently contribute to the reactivity of photocatalysts. Therefore, designing and constructing favorable surface atomic structure and electronic structure of photocatalysts for photocatalysis plays an indispensable role in overcoming the bottleneck of photocatalysis. Our effort mainly focuses on three aspects to reach such a goal, namely growing a large percentage of reactive facets, doping for favorable surface & bulk electronic structure, heterostructuring for efficient interface charge carrier transfer. Representative results will be introduced in this talk.
