摘　　要：采用Fe(NO_(3))_(3)·9H_(2)O和聚乙烯吡咯烷酮为原料,通过高温煅烧制备出Fe@N掺杂纳米碳催化剂(Fe-PVP-900-X,X=0.25、0.50、0.75;X代表不同Fe/C质量比),并探究了不同Fe/C质量比对催化剂催化性能的影响。其中,Fe-PVP-900-0.75在氧气还原反应(ORR)中表现出催化活性、且二电子路径选择性和稳定性良好。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(NO_(3))_(3)·9H_(2)O 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.
