- W2904951330 abstract "In this work, we developed a cost-effective, facile approach to obtain nitrogen self-doped porous biomass-derived carbon catalyst by direct co-pyrolysis of corn straw biomass with KOH. Through characterization, the obtained catalyst possesses a quite high BET surface area up to 1461.36 m2 g-1 and significant pyrrolic-N content. Electrochemical test demonstrated that nitrogen self-doped porous carbon exhibits an excellent electrocatalytic activity for oxygen reduction reaction (ORR) in alkaline media, with onset potential of -0.06 V (vs Hg/HgO) and current density of -3.42 mA cm-2, which is comparable to 20% Pt/C catalyst. More importantly, obtained catalyst shows high stability and durability towards ORR reaction. Our results demonstrated that the co-pyrolysis process is a promising route for economical and sustainable utilization of biomass towards the effective metal-free ORR catalysts for alkaline fuel cell." @default.
