Raspberry-like Pd3Pb alloy nanoparticles: Superior electrocatalytic activity for ethylene glycol and glycerol oxidation

Abstract

Pd3Pb catalysts are one of the state-of-the-art catalysts for the electrooxidation of alcohols. Herein, raspberry-like Pd3Pb catalysts are synthesized via a simple method. The materials are characterized using various physical techniques. The electrocatalytic behaviors of the products towards the oxidation of ethylene glycol and glycerol are investigated. Electrochemical results show that the raspberry-like Pd3Pb nanostructure produces excellent electrocatalytic activity and stability towards the electrooxidation of ethylene glycol and glycerol in alkaline media, which endows the prepared nanostructure with promising potential in applications like fuel cells.
