Zinc‐assisted synthesis of Fe‐N‐C catalysts based on polyaniline with high oxygen reduction reaction catalytic activities in direct methanol fuel cells
Abstract:Fe‐N‐C catalysts show great potential to replace Pt/C in oxygen reduction reaction (ORR). Polyaniline (PANI) is an ideal precursor with an abundant and homogeneous distribution of nitrogen sources. However, Fe‐N‐C based on PANI suffers from an unsatisfied performance in acidic media. Herein, a facile zinc‐assisted synthesis of Fe‐N‐C based on PANI was reported in this paper. ZnCl2 templates can be removed completely in the pyrolysis procedure, creating abundant porous structures to accelerate the mass transfer… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
