英文摘要this paper describes the preparation, characterization, and electrochemical properties of a porous dual-doped carbon composite. the composite is prepared by electrospinning of polyacrylonitrile solution with graphene oxide, and then incipient impregnating with fe(no3)(3) solution followed by calcination in n-2 atmosphere. the structure and composition of the composite are characterized by scanning electron microscopy, nitrogen adsorption isotherms, x-ray photoelectron spectroscopy, surface-enhanced raman scattering, and x-ray diffraction, respectively. under the optimal conditions, the resultant composite modified electrode exhibits excellent tolerance of methanol crossover, high current density (5.30 and 6.04 ma cm(-2) in alkaline and acidic solutions) and good durability (similar to 92.3% and 79.4% after 10,000 s in alkaline and acidic solutions, respectively) toward oxygen reduction reaction (orr). remarkably, the modified electrode displays a four-electron transfer process for orr. these above excellent electrocatalytic activity of the composite should be attributed to the synergistic effect of planar-n (pyridinic and pyrrolic n), fe-containing nanoparticles and reduced graphene oxide.
