▎ 摘　　要

A novel Pt/Cu-zeolite A/graphene based electrocatalyst was successfully prepared by chemical reduction method for methanol electrooxidation. Graphite oxide and Cu functionalized zeolite A were simultaneously reduced by NaBH4 to prepare Cu-zeolite A/graphene support which was used to deposit Pt nanoparticles. The nanostructure and composition of as-prepared Pt/Cu-zeolite A/graphene composites were characterized by X-ray diffractometer, X-ray fluorescence, Fourier transform infrared spectrometer and scanning electron microscopy. The electrocatalytic properties of Pt/Cu-zeolite A/graphene modified electrode for methanol oxidation were investigated by cyclic voltammetry and chronoamperometry in 0.10 mol/L H2SO4 + 0.50 mol/L CH3OH solution. Compared with Pt/zeolite A/graphene electrode and Pt/graphene electrode, Pt/Cu-zeolite A/graphene based electrode exhibited obviously enhanced current and higher electrocatalytic activity for methanol electrooxidation. The increased electrocatalytic activity was attributed to the presence of zeolite A and reduced graphene oxide based dual template, which significantly increased the effective electrode surface and facilitated the diffusion of analytes into the electroactive catalyst.
