Synthesis and structural characterization of a ternary palladium–ruthenium–tin nanoalloy supported on graphenenanosheets for methanol electrooxidation in alkaline medium

Abstract

A graphene-supported ternary Pd–Ru–Sn nanoalloy with a face centered cubic structure has been synthesized by a microwave-assisted polyol reduction method and investigated for electrooxidation of methanol in 1 M KOH at 25 °C. The electrocatalytic activity of the novel ternary alloy electrode is more than 2 times higher than that of the Pd/GNS (base) electrode. It is observed that the percentage increase in catalytic activity of the ternary alloy electrode in comparison with the base electrode increases with the electrolysis time during the chronoamperometry study.
