▎ 摘　　要

A novel palladium immobilized on reduced graphene oxide heterogeneous catalyst was prepared. The reduced graphene oxide was functionalized by imidazolium-based ionic liquids containing polyethylene glycol monomethyl ether moieties. The prepared catalyst can achieve Suzuki-Miyaura reactions efficiently in green solvents under mild conditions and could be recycled for five catalytic runs without the loss of activity.
