摘要

     Photocatalytic water splitting using a semiconductor photocatalyst has received much attention recently due to the potential of this method for the clean production of H2 from water utilizing solar energy. Although a number of metal oxides have been reported to be active photocatalysts for the water-splitting reaction, most only function under UV light owing to the large band gap energy of the materials. Since almost half of all incident solar energy at the Earth’s surface falls in the visible region, the efficient utilization of visible light remains indispensable for realizing practical H2 production. It is a great challenge to use visible light for photocatalytic processes. In this talk, I will highlight the efforts and findings in my group, with emphasis on (1) why the absorbed visible light by a photocatalyst makes negligible contribution to a photocatalytic process and (2) how to solve such an issue. Furthermore, an efficient visible light photocatalytic process for water splitting will be discussed.

 

學經歷

     I received my MS degree from Materials Science and Engineering at Feng-Chia University in 2004. I received my PhD degree from Materials Science and Engineering at National Chiao-Tung University in 2010. After graduation, I was selected as Academia Sinica Postdoctoral Fellow at Institute of Atomic and Molecular Science in 2011. Thereafter, I joined Dr. Jeffrey T. Miller’s group in Chemical Sciences and Engineering Division at Argonne National Laboratory as a postdoctoral researcher from 2012 to 2013. Currently, I am the assistant research scientist in National Synchrotron Radiation Research Center. I am the author and coauthor of 52 publications of journal articles in the field of energy conversion and storage application.
