Soybean straw biomass-derived Fe–N co-doped porous carbon as an efficient electrocatalyst for oxygen reduction in both alkaline and acidic media
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.
