文摘

CoOOH-PPy-C where Co was +3 valence was produced by impregnation-chemical way. CoOOH-PPy-C exhibited good electrocatalytic activity towards ORR. There was only 4% decrease of the cell voltage after operating for 80 h. The bonding of Co ion with N atoms should be a key issue regardless the valence of Co ion.
