Abstract

Pd nanocubes dispersed on graphene oxide were prepared by the reduction of PdCl42−. In this method,graphene oxideactedasboth surfactant and support.The as-prepared Pd nanocubes/graphene oxidecatalyst exhibited higher electrocatalytic activity and stability than a commercial Pd/C catalyst for methanol and formic acid oxidation.
