The capability to design innovative semiconductor materials with desirable functionalities is a highly challenging task. In this talk, we give a brief overview of our recent progresses in designing semiconductor metal oxides materials for photoelecttrochemical energy conversion including photocatalytic solar fuel generation and low cost solar cells. In more details, we have been focusing the following a few aspects; 1) band-gap engineering of layered semiconductor compounds including layered titanate, tantalite and niobate-based metal oxide compounds for visible light phtocatalysis, and 2) two-dimensional nanosheets/nanoplates of TiO₂, Fe₂O₃ and WO₃ as building blocks for new photoelectrode design, and 3) the design of semiconductor nanoparticles for low cost solar cells including perovskite solar cell applications.^1-5 The resultant material systems exhitited efficient visible light photocatalytic performance and improved power conversion efficiency in solar energy, which underpin important solar-energy conversion applications including solar electricity and sola fuel production.
