Abstract

Pt-supported reduced graphene oxide (Pt/RGO) catalysts were prepared over the RGO sheets with different sizes for methanol oxidation and oxygen reduction reactions in acidic media. The Pt on the smaller RGO presented higher catalytic activities than the Pt on the larger RGO and the commercial Pt/C catalyst.
