摘      要：We report a solvothermal method preparation of dendritic Pd nanoparticles （DPNs） and spherical Pd nanoparticles （SPNs） supported on reduced graphene oxide （RGO）. Drastically different morphologies of Pd NPs with nanodendritic structures or spherical structures were observed on graphene by controlling the reduction degree of graphene oxide （GO） un- der mild conditions. In addition to being a commonplace substrate, GO plays a more important role that relies on its surface groups, which serves as a shape-directing agent to direct the dendritic growth. As a result, the obtained DPNs/RGO catalyst exhibits a significantly enhanced electro-catalytic behavior for the oxidation of formic acid compared to the SPNs/RGO catalyst.
