Biomass waste-derived nitrogen and iron co-doped nanoporous carbons as electrocatalysts for the oxygen reduction reaction

•Biomass-derived carbons are appropriate precursors for fuel cell electrocatalysts.•Microporosity and graphitic domains play a determining role in electroactivity.•Catalysts become active upon two thermal treatments and one acid etching.•Fe-N4-C and nitrogen functionalities are created on activated...
