Shell structure-enhanced electrocatalytic performance of Au–Pt core–shell catalyst

Abstract

This paper describes the preparation of Pt nanorods by directly growing them on the surface of Au. Electrochemical measurements were performed to investigate their catalytic performance towards methanol oxidation. It was found from cyclic voltammetry that the Pt nanorods supported on Au nanoparticles had excellent steady-state catalytic activity and high catalytic activity for methanol electrooxidation. They also exhibited a slightly slower current decay over time.
