摘要	Iron-nitrogen (Fe-N) sites confined within carbon are highly active to catalyze the oxygen reduction reaction (ORR). The mesoporous structure of carbon facilitates the mass transport and availability to the Fe-N sites during the ORR; however, the construction of mesoporous carbon architecture with highly exposed and accessible Fe-N active sites remains challenging. Herein, 3D-to-2D transformation of zeolitic imidazolate frame-work-7 (ZIF-7) was successfully achieved via convenient impregnation in ammonium ferric citrate aqueous solution. After pyrolysis, isolated Fe-N sites are generated and confined within highly mesoporous carbon without using any additional modulator or template. The optimal Fe-N catalyst exhibits excellent performance toward ORR in alkaline medium, exceeding commercial 40% Pt/C catalyst in terms of activity, stability, and methanol resistance.
