中文摘要	non-precious metal catalysts (npmcs) for the oxygen reduction reaction (orr) are an active subject of recent research on proton exchange membrane fuel cells. in this study, we report a new approach to preparation of self-supported and nano-structured npmcs using pre-prepared polyaniline (pani) nanofibers as both nitrogen and carbon precursors. the synthesized npmcs possess nanoworm structures preserved from the pani precursor and exhibit high onset potential of 0.905 v vs. rhe and selective activity of nearly four-electron orr pathways. a significant enhancement in the intrinsic activity and onset potential for the orr is observed when the fe content in the precursor is increased from 0 to 3.0 wt.%, while further addition to 10.0 wt.% results in a decrease in the catalytic activity. crown copyright (c) 2012 published by elsevier b.v. all rights reserved.
