Developing non-PGM electrocatalysts with both high selectivity and durability for the oxygen reduction reaction (ORR) is critical for several applications including fuel cells and metal-air batteries. Pyrolytic synthesis of nitrogen and transition metal (Fe, Co or Mn) co-doped carbon recently appeared as an attractive approach for developing ORR catalysts with activities comparable with the commercial Pt/XC-72r. In this presentation, we will discuss our recent research on exploring the structural control of carbon during the pyrolytic process. We will introduce a molten salt mediated strategy for synthesizing PGM-free catalysts with higher materials yield, better activity and durability. The structure-performance relationship of these catalysts will be discussed.
