A copper nanoparticle decorated three-dimensional graphene nanocomposite was prepared at room temperature by reduction of copper sulfate using l-ascorbic acid as the reducing agent.
Cu nanoparticles with average particles size around 10 nm were incorporated on the surface of a mesoporous carbon nitride support. The XRD and N 2 adsorption isotherms show that it maintains a hexagonal mesoporous structure with a high surface area (600.03 m 2 g
−1). The embedded Cu nanoparticles exhibit extremely high catalytic performance in two different kinds of organic reactions. The Huisgen 1,3-dipolar cycloaddition and N-arylation of N-heterocycles were all accomplished.
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.
