摘要：

MOFs-derived nitrogen -doped porous carbon nanosheets Fe@Co/N@PCN were prepared by pyrolysis using Fe@Co/Zn-MOFs and g-C3N4 as precursor templates.The effects of metal doping on the catalytic activity of MOFs carriers were investigated by morphological structure and electrochemical performance characterization. It was found that the addition of bimetals not only increased the specific surface area of the catalysts, but also had a synergistic catalytic effect, resulting in a half-slope potential of 0.872 V vs. RHE in Fe@Co/N@PCN in 0.1 M KOH, and its ORR electrocatalytic activity, stability and methanol resistance were better than those of commercial Pt/C catalysts.
