The experimentaland theoretical workshop on photocatalysis was held in DICP on August 30^th-31^st.This workshop was initiated by Prof. Lemin Li (Peking University)and Prof. Can Li (DICP). About seventy participants attended the workshop,including thirty scientists well-established in photocatalytic field from both institutesof Chinese Academy of Sciences and universities, togetherwith research staffs and Ph.D. students in the Division of Solar Energy, DalianNational Laboratory for Clean Energy.

The theme ofthis workshop was focused on the key scientific issues in photocatalysis fromthe aspects of experiment and theory. The extensive discussion covers thephoto-harvesting, photo-generated charge separation and catalytic efficiency. Solarphotocatalysis is a promising approach to provide clean and renewable energyfor human being. But constructing an efficient system to realize this reactionunder sunlight irradiation is still a great challenge. The common views of allthe participants point out that the strong collaboration between the experimentand theory is absolutely necessary for achieving the progress in this field.
