Fe@N doped nano-carbon catalysts(Fe-PVP-900-X,X=0.25,0.50,0.75,X represents different Fe/C mass ratios)were prepared using Fe(NO3)3·9H2O and polyvinylpyrrolidone as raw materials in different mass ratios and calcining at high temperature.The influence of different Fe/C mass ratios on the catalytic performance of catalysts was explored.Fe-PVP-900-0.75 showed outstanding performance in ORR catalytic activity,two electron path selectivity and stability.
