Efficient electrooxidation of biomass-derived glycerol over a graphene-supported PtRu electrocatalyst

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.

Research highlights
► The PtRu/GNS is prepared via simple surfactant-free synthesis processes.
► The PtRu/GNS demonstrates high activity compared to the conventional Pt/C for glycerol electrooxidation.
► This work represents a new attempt at using layered GNS supports for glycerol electrooxidation.
