　　报告简介：

　　Solar energy has the potential to meet a significant fraction, if not all, of the increasing global energy demands. Among the approaches of solar energy conversion and storage, water splitting to renewable hydrogen and CO2 photoreduction by sunlight have been attracting more and more attention over the last ten years after a long-term silence. Solar irradiance is diffuse and intermittent, thus solar energy utilisation requires economically viable conversion technologies to be both efficient and low cost.

　　To achieve an efficient photocatalyst for solar energy storage remains a big challenge, involving Material Science, Chemistry, Engineering and Physics. Recently we preliminarily illustrated the key factors dominating solar energy conversion efficiency in the solar driven water splitting.1 Stimulated by these outcomes, we further developed novel material strategies for solar driven hydrogen synthesis and CO2 reduction. In this lecture, I will present the recent results obtained in my group including the facets controlled Ag3PO4 which shows the highest activity for water photooxidation reaction under visible light.2 On the other hand, highly polymerised C3N4 demonstrates an extremely high H2 production rate from water, leading to a 26% quantum efficiency,3 one order of magnitude increase compared with the previous report.4 Furthermore, pure water splitting for simultaneous H2 and O2 evolution by an organic semiconductor based system in a suspensions solution has been firstly demonstrated.5 In parallel, junction structure for CO2 photoreduction to CO under visible light irradiation will be addressed in the lecture.6
