Facile synthesis of porous Pt-Pd nanospheres supported on reduced graphene oxide nanosheets for enhanced methanol electrooxidation

In this work, we report a simple and facile wet-chemical route for preparation of uniform porous Pt-Pd nanospheres supported on reduced graphene oxide nanosheets under ambient temperature, without the need of premade seed, organic solvents or special apparatus. The as-prepared hybrid composites displayed enhanced electrocatalytic activity and better stability toward methanol oxidation.244
