Dr. WU was invited to deliver an oral presentation at Tsinghua Shenzhen International Graduate School (SIGS).  The topic is about manipulating charge dynamics in photo(electro)catalysis. SEECAT group also did a research visit at the Department of Materials Science and Engineering and the Institute of Environment and Ecology of Tsinghua SIGS. It was indeed a great pleasure to exchange ideas with young academicians who share the same goal.
