Methanol electro-oxidation on Pt-modified Au nanoparticles was studied in aqueous 0.5 M H 2 SO 4 /1 M CH 3 OH. The Pt-modified Au nanoparticles showed lower values than pure Pt nanoparticles in area-specific current densities. The activity also decreased with lower amounts of Pt on the Pt-modified A

## Abstract A comparative study between carbon supported Platinum–Tin (Pt–Sn~syn~), synthesized via the carbonyl route, and the commercial (Pt~3~Sn) from E–TEK is reported. The electro‐oxidation of methanol and adsorbed CO, in sulphuric acid medium, were used as probes to evaluate the performance o
