We utilize our expertise in surface chemistry and catalysis to develop innovative catalytic materials for sustainable energy applications. A process of particular interest is solar fuel generation by CO2 reduction using molecular catalysts and single-atom catalysts on solid-state surfaces. Spectroscopic, microscopic, and electrochemical techniques are employed to characterize such catalytic materials and establish structure-function relationships. In addition, we integrate research with education by organizing STEM workshops for K-12 science teachers and students. Our projects have received support from the U.S. Department of Energy (DOE) and National Science Foundation (NSF), including a prestigious NSF CAREER Award.
The Li group is currently accepting new graduate students.
