Ni nanoparticle supported reduced graphene oxide as a highly active and durable heterogeneous material for coupling reactions

We report the loading of highly air stable Ni(0) nanoparticles (average particle size = 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...

Description
Summary:We report the loading of highly air stable Ni(0) nanoparticles (average particle size = 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 4-methoxybiphenyl at 60 °C. The recycled material can be reused up to the 5 th cycle after regeneration by calcination, without loss of activity. Ni nanoparticle supported reduced graphene oxide is shown to be a highly active and durable heterogeneous catalyst for Kumada-Corriu cross-coupling reactions.
