Coordination compound-derived Fe4N/Fe3N/Fe/CNT for efficient electrocatalytic oxygen evolution: a facile one-step synthesis in the absence of extra nitrogen source
Abstract:By annealing an Fe(III)-coordination compound (Fe-CC), [FeCl3(Hbta)2] (Hbta = benzotriazole) in the presence of a CNT template, an Fe4N/Fe3N/Fe/CNT heterostructure was successfully synthesized without extra nitrogen source. The decomposition of the Hbta in Fe-CC under high temperature annealing can produce carbon sheets and graphene, and the presence of CNT can alleviate the stacking of the in-situ generated carbon materials. Meanwhile, iron nitride nanoparticles (NPs) can be anchored on the carbon sheets, and… 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.
