▎ 摘　　要

We report very small and highly dispersed PtRu nanoparticles on a graphene support prepared via simple surfactant-free synthesis processes, which demonstrate excellent activity and stability compared with conventional Pt/C and bimetallic PtRu/C for the electrooxidation of biomass-derived glycerol.
