▎ 摘　　要

We report the loading of highly air stable Ni(0) nanoparticles (average particle size 1/4 11 nm) on the surface of a reduced graphene oxide (RGO) material. The material was characterized using different techniques, including Raman spectroscopy, XRD, TEM, SEM, and HRTEM analysis. The Ni(0)@ RGO catalyst showed superb efficiency towards Kumada-Corriu C-C cross-coupling reactions, with 92% yield of 4methoxybiphenyl at 60 C. The recycled material can be reused up to the 5th cycle after regeneration by calcination, without loss of activity.
