【Title】Heteroatom-Doped Carbon Nanomaterials and their Composites: Sustainable Catalysts for Fuel Cells and Water Splitting
Time: 10:00 am, May 24th, 2019
Location: New MSE Building, No. 01 Meeting Room (新材料大楼材料学院第一会议室)
Abstract:The lack of sustainable and efficient catalysts for many renewable energy applications (e.g., fuel cells and water splitting) and the unabated negative environmental impacts of fossil fuels remain among the most pressing issues facing the world today. In this talk, my research group’s recent efforts on the synthesis of catalytically active nanostructured and nanoporous heteroatom-doped, metal-free or noble metal-free materials and their composites. These materials are found to exhibit high catalytic and catalytic activities for reactions such as the oxygen reduction reaction (ORR), the hydrogen evolution reaction (HER), the oxygen evolution reaction (OER), and the hydrazine oxidation reaction (HOR)—reactions that are relevant to fuel cells and water splitting, or renewable energy in general—will be discussed. Particular focus will be given to the various novel design, “nanostructuring” and heteroatom doping synthetic approaches employed in my group to make a series of efficient catalysts. Moreover, fundamental and theoretical studies that helped us to unravel catalytic active sites on some of these materials and the mechanisms by which they effectively catalyze some of these hard-to-catalyze reactions in fuel cells and electrolyzers will be discussed.
