Large-scale amorphous metal oxide films deposited on arbitrary substrates via redox interaction exhibit greater efficiency and durability in electrocatalytic oxygen evolution than benchmark materials.
Discontinuous cobalt manganese oxyhydroxide (CMOH) film shows much higher atom efficiency and performance in the oxygen evolution reaction (OER) than the completely continuous ones. In article number 1903363, Jiaxing Huang, and Chun‐Hu Chen, and co‐workers prove that the heterojunction edges are responsible for the OER enhancement with facilitated charge transport and kinetics. This concept is highly valuable for reducing the catalysts dosage but gaining even better, durable OER activities.
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.
