英文摘要	Developing an efficient, easy-to-fabricate and applicable noble-metal-free catalyst for the oxygen reduction reaction (orr) is extremely necessary for fuel cells. in this context, by pyrolyzing a nontoxic and low-cost iron-coordinated polydopamine polymer (fe-pda-30, 30 represents the polymerization time) precursor at 800 degrees c, a template-free oxygen reduction reaction (orr) catalyst iron and nitrogen co-doped hierarchical porous graphitic carbon (fe, n/pgc-30) was obtained. the obtained catalyst fe, n/pgc-30, first reported here, manifests outstanding oxygen reduction activity in a wide range of ph. it is worth nothing that the catalyst exhibits remarkable orr activity with a more positive half-wave potential of 15 mv than that of the commercial pt/c catalyst under alkaline conditions. additionally, the activity of the catalyst is comparable to that of commercial pt/c under neutral and acidic conditions with almost a 4e(-) reaction process and very low h2o2 yield. this catalyst provides an exciting direction for non-precious metal electrocatalysts with excellent oxygen reduction activity in a wide range of ph. these favorable results demonstrate that the catalyst fe, n/pgc-30 can serve as a highly efficient and stable orr catalyst for practical fuel cell applications.
