Abstract:A series of carbon black supports with different surface chemical state were prepared with the oxidation treatment of Vulcan XC-72 carbon black.Pt/C catalysts were fabricated with formaldehyde as the reducing agent and hydrochloroplatinic acid as the precursor.The chemical composition,chemical state,crystal structure and surface morphology of carbon black supports and Pt/C catalysts were respectively studied by X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD)and transmission electron microscope(...
Keywords:oxidation treatment  oxygen-containing functional group  anchor site  electrocatalytic activity
