报告人： Hailiang Wang (王海梁), Yale University
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 solidquid 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.
