UPRIGHT FEW-LAYER GRAPHENE-METAL NANOPARTICLE COMPOSITE CATALYTIC ELECTRODE

摘要

Disclosed is an upright few-layer graphene-metal nanoparticle composite catalytic electrode, comprising: a conductive substrate, upright few-layer graphene layers, and metal nanoparticles. The present invention also relates to a preparation method for the composite catalytic electrode. The composite catalytic electrode has high effective surface area and metal utilization, and greatly reduces the amount of a precious metal and industrial costs. The preparation method compounds nanoparticles by means of a magnetron sputtering method, and has simple and convenient preparation steps, the size morphology of the metal particles is controllable, and the purity is high.
