Abstract:A soft-pyrolysis strategy by heating Co-N-implanted covalent organic polymer combining on carbon nanotubes at ≤500 °C has been developed to obtain efficient Co-N-C electrocatalysts for oxygen reduction reaction (ORR). The prepared Co-N-C is highly active for ORR with a half-wave potential of 0.91 V versus RHE in 0.1 M KOH electrolyte, superior to most of previously reported Co-based electrocatalysts. When employing it as cathode electrocatalyst, the homemade Zn-air battery shows a peak power density of 304.2 m… 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.
