▎ 摘　　要

Three reduced graphene oxide (rGO) with different defect contents were prepared at 250, 600 and 1000(circle)C, respectively, using thermal reduction method, and their effects on the oxidative coupling processes of 4-methoxyphenol (MOP) in aqueous solution were investigated. In the presence of rGOs, the oxidation of MOP was dramatically accelerated. At the same surface area dose, the catalytic efficiencies of three rGOs followed an ascending order of rGO(250)
