▎ 摘　　要

A copper(II) complex grafted to nitrogen-doped graphene (GrN(700)-CuC) was synthesized and then demonstrated as an efficient photocatalyst for CO2 reduction into methanol under visible light irradiation using a DMF/water mixture. The chemical and microstructural features of GrN(700)-CuC nanosheets were studied by FTIR, XPS, XRD and HRTEM analyses. Owing to its truly heterogeneous nature, GrN(700)-CuC could be easily recovered after the photocatalytic reaction and showed efficient recyclability for subsequent runs.
