- •
We prepared an efficient Pt-Au-RGO architecture using an effective strategy to enhancing loading of Au nanoparticles into RGO.
- •
The electrochemically active surface area (ECSA) of the Pt-Au-RGO heterogeneous electrocatalyst is found to be higher than the Pt-RGO and Pt/C electrocatalysts.
- •
The Pt-Au-RGO electrocatalyst demonstrated better electrocatalytic activity and stability than the Pt-RGO or Pt/C black for methanol oxidation.
