Fe–N co-doped porous carbon (Fe–N–PC) was prepared by a facile one-step pyrolysis strategy using biomass soybean straw as the precursor, which exhibits outstanding electrocatalytic performance for ORR, excellent stability and methanol tolerance.
The advancement of electrocatalysts using non-precious metal with excellent catalytic ability and durability for oxygen reduction reaction (ORR) remains an enormous challenge. Transition metal-nitrogen-carbon (M-N-C) materials become target products with...
