- Abstract
The improved Hummers method was used to prepare the graphene oxide. Then, using the precursor as the carrier and the triblock copolymer P123 as the reductant, the protective agent and the morphology control agent, the liquid phase co-reduction method and the continuous reduction method were respectively used to prepare the graphene oxide Three graphene-supported Pt Pd (Pt Pd / G) nanocatalysts were synthesized. The graphene oxide and the metal precursor were simultaneously reduced to achieve the in-situ loading effect. The morphology, structure and composition of Pt Pd / G nanocatalyst were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results showed that both catalysts were nanodiesel structures. Hollow nanostructures were obtained by continuous reduction method. Electrochemical cyclic voltammetry and chronoamperometry showed that the Pt Pd / G nanocatalysts with the hollow structure were the most resistant to CO poisoning and the Pt Pd / G nanocomposite catalysts synthesized at 100 ° C had the best electrocatalytic oxidation Methanol performance, about 1.5 times the commercial Pt / C catalyst.
