Graphene support for enhanced electrocatalytic activity of Pd for alcohol oxidation

Author affiliations

Abstract

Graphene nanosheets (GNS) were synthesized by the NaBH4 reduction of freshly prepared graphite oxide and utilized as a catalyst support of palladium nanoparticles for the electrooxidation of ethanol and methanol. Home-made GNS were characterized by Raman spectroscopy and XRD. The study has shown that Pd nanoparticles dispersed on GNS were highly active for the electrooxidation of ethanol and methanol in 1 M KOH. It is observed that Pd nanoparticles dispersed on GNS are more active compared to those dispersed on nanocarbon particles (NC) or multiwall carbon nanotubes (MWCNTs) for ethanol/methanol electrooxidation under similar experimental conditions. The enhanced electrochemical activity of Pd/GNS toward alcohol oxidation can be ascribed to the greatly enhanced electrochemical active surface area of Pd nanoparticles on the GNS support.
