▎ 摘　　要

By combining alloying and supporting approaches, ternary alloy CuFePt nanocatalysts anchored on the reduced graphene oxide (RGO) have been facilely synthesized by using NaBH4 as reductant in an ambient one-pot strategy. The as-prepared CuFePt/RGO hybrids were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), energy-dispersive spectrometry (EDS), and transmission electron microscopy (TEM). The electrochemical measurements showed that the ternary CuFePt/RGO exhibited a highly enhanced electrocatalytic activity and improved stability for the methanol oxidation reaction (MOR) and formic acid oxidation reaction (FAOR), much superior to those of binary CuPt/RGO and FePt/RGO, and mono-metallic Pt/RGO counterparts. The atomic composition ratios of Cu and Fe in CuFePt/RGO were also optimized to probe their influences on electrocatalytic performance. The straightforward synthesis of ternary CuFePt/RGO provides a promising strategy for development of high-performance Pt alloy catalysts for both MOR and FAOR in fuel cells. (C) 2015 Elsevier Ltd.
