Freestanding ultrathin metallic nanosheets (FUMNSs) with atomic thickness attract extensive attention because they display remarkable advantages over their bulk counterparts by virtue of their large specific area, high aspect ratio, and unsaturated surface coordination. The state of the art of research on FUMNSs is reviewed here, wherein the important progress from the aspects of material category, synthetic strategy, and practical application are introduced, and it is demonstrated that FUMNSs will play an important role in the fields of optoelectrics, catalysis, and magnetism.
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.
