Abstract:Modification with transition metal compounds is an effective strategy to improve the capacitance of biomass derived carbon. In this work, high‐performance (Ni,Co)Se/banana leaves derived carbon ((Ni,Co)Se/BLC) composite with 3D porous structure was prepared by two‐step carbonization and subsequent hydrothermal reaction process. The prepared (Ni,Co)Se/BLC exhibits a high specific capacitance of 840.6 F/g at a current density of 1 A/g, which is more than five times comparing with the carbon matrix. Asymmetric su… 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.
