Development of non-precious-metal electrocatalysts is believed as the key for realization of scale-up applications of the proton exchange membrane fuel cells.[1] One of the most promising types of non-precious-metal catalysts is carbon-supported transition metal-nitrogen (C/M-Nx) materials (M=Co,Fe,Ni,Mn,etc.,and normally x =2 or 4).[2]
