▎ 摘　　要

Solvothermal graphene (SG) in a bottom-up approach was used as a support, and a PtRu/SG catalyst was prepared by a modified impregnation method. The results showed that the PtRu nanoparticles were uniformly dispersed on the SG with average particle size of 2.6 nm. The PtRu/SG catalyst showed a large electrochemical active surface area (59.95 m(2) g(-1)) and high catalytic activity toward oxidation of methanol.
