Dopamine, a sustainable and cheap raw material, was selected as the carbon and nitrogen sources to synthesize hollow nitrogen‐doped carbon microspheres (HNCMS). The obtained HNCMS were used as a non‐noble‐metal electrocatalyst for oxygen reduction in alkaline solution and show high electrocatalytic activity, excellent long‐term stability, and tolerance to crossover effect of methanol.
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.
