摘要: A facile one-step synthesis of the hybrid hierarchical nitrogen-doped porous carbon and Fe3C nanoparticles encapsulated a nanotube through simply annealing mixture FeCl3, o-phthalic anhydride, melamine at 800 °C in Ar was proposed. Both specific ratio these precursors selected temperature are key factors for formation unique structure, while any subtle modulation will result different morphologies. Thanks to good conductivity diversity, Fe–N–C material obtained exhibits half-wave potential 0.880 V, ca. 50 mV more positive than Pt/C, oxygen reduction reaction (ORR) an overpotential 0.41 36 lower IrO2 black, current 10 mA cm–2 evolution (OER).
