    1999年赴澳大利亚新南威尔士大学攻读博士学位。2003年获博士学位后,先后于美国内布拉斯加州大学林肯分校化学系(博士后)、美国劳伦斯伯克利国家实验室(博士后、项目研究员)工作,主要从事二氧化碳的光催化还原降解和水的可见光催化氧化。2009年以“百人计划”引进,聘为洁净能源国家实验室(筹)太阳能研究部研究人员,创新特区研究组组长,并加盟催化基础国家重点实验室李灿院士的503组工作。

 

 

前期工作主要涉及电子给体--电子受体(D-B-A)在非均相体系中的电子转移及其长寿命电荷分离态研究,水的可见光催化氧化,二氧化碳的光催化还原降解,以及自由基化学。

         现在的研究工作将主要围绕太阳能转化为太阳能燃料(solar fuel)和绿色光催化领域:(1)光催化分解水制氢;(2)光催化分解H2S制氢;(3)光催化重整生物质制氢;(4)光催化还原降解CO2制备化学燃料;(5)可见光催化分解有机物。在整个研究过程中,可见光响应的催化材料、体系的制备,电子转移及其长寿命电荷分离态机理的研究将贯穿始终。寻找可替代化石燃料(煤、石油、天然气)的、可再生的洁净能源是21世纪人类社会所面临的一个重大挑战,而太阳能光-化学转化制氢构建氢经济(hydrogen economy)是未来洁净能源的最佳方向。
