Sustainable energy utilization and carbon emission reduction are critical challenges for the world. Solving these challenges requires precise control of many important chemical reactions with sluggish kinetics and myriad possible reaction pathways and associated products. There is a critical need for selective, active, durable and low-cost catalysts. This poster presents our research efforts in studying material structures and properties at solid/liquid interfaces under electrochemical conditions and in establishing design principles for new and improved catalysts for the electrochemical conversions of CO2 to fuels and other useful chemicals. We are particularly interested in remarkable catalytic reactivity enabled by multi-component interactions or by restructuring under working conditions. We develop heterogeneous electrocatalyst materials comprising molecular-structure catalytic sites that can be designed and optimized at the molecular level. We also make use of the knowledge derived from the molecular systems to create heterogeneous nanoparticle electrocatalysts that mimic the configurations and functionalities of molecular catalyst systems via strong metal-metal phosphide, metal-metal oxide and metal-metal interactions. We further refine our catalyst materials beyond the catalytic site structures and incorporate them in electrochemical devices to deliver higher performance and new functionalities.

Hailiang Wang is an Assistant Professor in the Department of Chemistry at Yale University. He is also a faculty member of the Energy Sciences Institute on Yale West Campus. Prior to joining Yale in 2014, he was a Philomathia Postdoctoral Fellow in the Department of Chemistry at University of California, Berkeley. He received his Ph.D. in chemistry from Stanford University in 2012 and B.S. in chemistry from Peking University in 2007. His research aims to understand the molecular-level chemical processes at solid/liquid interfaces under electrochemical conditions and to establish design principles for new and improved electrocatalyst and battery materials. He is a winner of the US NSF CAREER award, and a Web of Science Highly Cited Researcher. He has published more than 90 journal articles with total citations of 27,000 and an h-index of 49 (Google Scholar).
