Abstract:Constructing efficient and cost-effective oxygen reduction reaction (ORR) electrocatalysts in wide pH ranges is important for renewable energy storage and conversion devices. As prospective alternatives to commercial Pt/C electrocatalysts, transition-metal (TM) single-atom catalysts (SACs) delivered limited catalytic activity and stability in a wide pH range, especially in acidic and neutral electrolytes. Herein, we demonstrate a general synthesis strategy for preparation of TM SACs via the MgO template-assist… 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.
