Chemical reduced graphene oxide/AuPtPd nanocomposite for enhanced electrocatalytic ability

Trimetallic nanoparticles (AuPtPd) were synthesized and in-situ assembled on the surface of chemical reduced graphene oxide (CRGO). The obtained CRGO-AuPtPd composite was then characterized by transmission electron microscopy (TEM), X-ray energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) techniques. In cyclic votammogram (CV) tests, CRGO-AuPtPd showed to be a more active catalyst for methanol, ethanol and formic acid oxidation in 0.5 M H2SO4 solution than the same AuPtPd nanopartcles without CRGO. This work demonstrated that CRGO is a promising support to improve the catalytic performance of nanoparticles. (C) 2012 Elsevier B.V. All rights reserved.
