| 英文摘要 | nitrogen-doped carbon nanofibers (ncnfs) are prepared by the thermal treatment of carbon nanofibers (cnfs) using urea as nitrogen source. scanning electron microscopy, transmission electron microscopy and x-ray photoelectron spectroscopy have been employed to characterize the morphology and composition of cnfs and ncnfs. compared with cnfs, ncnfs display thinner diameter, rougher surface and higher content of pyrrolic-n. as a metal-free catalyst for orr, ncnfs exhibit comparable catalytic activity, significantly enhanced long-time stability and selectivity in comparison with commercial available pt/c catalyst. importantly, the self-supported ncnfs films could be conveniently utilized for electrode modification which is attractive in fuel cells. this work offers a promising metal-free catalyst as an alternative for pt/c catalyst.
