报告内容简介：
Semiconducting materials hold the key for efficient photocatalytic and photoelectrochemical water splitting. In this talk, we will give a brief overview of our recent progresses in designing semiconductor metal oxides materials for photoelectrochemical energy conversion including photocataly tic solar fuel generation. In more details, we have been focusing the following a few aspects: 1)band-gap engineering of layered semiconductor compounds including layered titanate, tantalate and niobate-based metal oxide compounds for visible light phtocatalysis, and 2)two-dimensional nanosheets nanoplates of TiO2, Fe2O3, WO3, BiVO4 as building blocks for new photoelectrode design, and 3) the combination of a high performance photoclectrodes with new generation perovskite solar cells can lead to unassisted solar driven water spliting process with solar-io-hydrogen conversion efficiency of >6.5%.1-6 The resultant matcrial systcms exhibited efficient visible light photocatalytic performance andimproved power conversion efficiency in solar energy, which underpin imporLant solar-energy conversion applications including solar fuel generation. and low-cost high efficiency solar cells.
