Abstract

Two kinds of phosphorus-modified onion-like carbons dominated by COP bonds and CP bonds were fabricated and further used as catalysts in the oxygen reduction reaction (ORR). The results show that the bonding state of phosphorus has a significant effect on the ORR catalytic activity. The formation of COP bonds improves ORR activity, whereas CP bonds play an adverse role in stabilizing the key intermediates during the ORR owing to the distorted graphitic structure, as confirmed by the work function value.
