Graphene Decorated with PtAu Alloy Nanoparticles: Facile Synthesis and Promising Application for Formic Acid Oxidation

Abstract

PtAu/graphene nanocomposites with high activity toward formic acid oxidation were synthesized in the presence of poly(diallyldimethylammonium chloride), which not only acted as “nanoreactors” for the preparation of PtAu alloy NPs but also facilitated the uniform loading of PtAu NPs on graphene nanosheets.
