Abstract In this study, a green, efficient, recyclable Cu2O nanoparticles on reduced graphene oxide (Cu2O-NPs@rGO) carbon-based composite catalyst was synthesized by facile one-pot hydrothermal method. And Cu2O-NPs@rGO catalyst was characterized by XRD, XPS, TEM, SEM, SEM-EDS and ICP-OES to explore its morphology, structure and chemical composition. The heterogeneous catalyst shows great catalytic performance and excellent functional group tolerance in the oxidative coupling of aryl methyl ketones and secondary amines leading to α-ketoamides with O2 and N-iodosuccinimide (NIS) under room temperature. Furthermore, Cu2O-NPs@rGO exhibits good recyclability, which was reused seven times without obvious decline in the catalytic activity.
