Abstract:Advancing electrode materials with high adsorption capacity and fast rate is crucial for seawater desalination in capacitive deionization (CDI).Here, we propose a highly oriented, densified graphene (HODG) electrode characterized by its ordered/short ion transport channels, abundant oxygen functional groups, high packing density (1.374 g cm −3 ), and large specific surface area (543.72 m 2 g −1 ), facilitating exceptional fast ion diffusion and ultrahigh volumetric desalination capacity. HODG delivers a volume… 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.
