报告摘要：
　　The study of photocatalysis has received great attentions from chemists, physicists as well as material scientists because of its important applications in energy and environmental sciences. In the last few years, we have developed experimental techniques in our laboratory to target the photocatalysis problem. Using the 2PPE technique and the TOF-TPD technique in combination with laser-surface photocatalysis, we have investigated the problems of photocatalytic dissociation of methanol and water on TiO2(110). Important insights have been learned from these experiments. In this lecture, I will present some new thinkings on surface photocatalysis based on our own experiments, especially on what is really driving surface chemical reactions after the initial electron-hole pair excitation.

报告人简介：
　　Dr. Xueming Yang obtained his Ph.D. in chemistry from University of California at Santa Barbara in 1991. After postdoctoral experiences at Princeton and UC Berkeley, he started his research career at the Institute of Atomic and Molecular Sciences in Taipei in 1995. He was promoted to a tenured fellow at IAMS in 2000. He then made a move to the Dalian Institute of Chemical Physics, CAS in 2001, and became the director of the State Key Laboratory of Molecular Reaction Dynamics. He is also a professor in chemical physics at USTC. His research interests are mainly in the area of chemical physics in the gas phase and at surfaces. He has published more than 200 peer reviewed papers, including 9 in Science and 1 in Nature. During his research tenure, he has received many prestigious awards including the Broida Prize, the Achievement in Asia Award, the HeLiangHeLi Award, the Tan Kah Kee Science Award, and Humboldt Research Award. He is an elected fellow of APS and a member of CAS.
