Porous Carbon Spheres with Ultra-fine Fe2N Active Phase for Efficient Electrocatalytic Oxygen Reduction
In this work, hierarchically porous carbon spheres co-doped by iron and nitrogen were synthesized via in situ dehalogenation. The rich porous structure and relatively high specific surface area (210 m 2 /g) facilitate the formation of an ultra-fine Fe 2 N active phase and FeN 4 active centers within...
