Abstract

Oxygen reduction reaction (ORR) is being deeply studied because of its significance in energy storage and conversion. It is an urgent and challenging task to explore low-cost ORR catalysts with excellent activity and outstanding long-term stability. Herein, we report an efficient bimetallic FeCo catalyst based on nitrogen-doped carbon (FeCo−NC) for ORR by pyrolysis of FeCo-1,10-phenanthroline complexes (FeCo-phen) supported on ZIF-8. The as-synthesized FeCo−NC catalyst shows excellent ORR activity, improved durability and excellent methanol cross poisoning resistance, which are ascribed to the formation of metal-N−C active sites, the synergistic effect between Fe and Co, as well as the porous structure.
