报告摘要:
Fuel cells and metal air batteries are promising techniques for innovative energy conversion and storage. The commercialization of these techniques requires the earth-abundant efficient and durable electrocatalysts for oxygen reduction reaction (ORR) and/or oxygen evolution reaction (OER). Their performances are closely related to the intrinsic activity and the number of the accessible catalytic sites in the electrocatalysts. This presentation will focus on the development of high-density earth-abundant metal-nitrogen-carbon active sites for advanced ORR and OER electrocatalysts. A couple of new strategies will be introduced, including a molecular-based cascade anchoring strategy for general mass production of high-density metal-nitrogen single-atomic catalysts for diverse electrocatalytic applications, metastable rocksalt oxide mediated synthesis of high-density well-armored transition metal nanoparticles for boosting power density and cycling life of zinc-air batteries, etc. These results may give new insights for the rational design and bottom-up synthesis of cost-effective and high-performance electrocatalysts for diverse advanced energy-related devices.
