dc.description.abstractThe efficiency of the direct methanol fuel cell (DMFC) is related to the dispersion of the metal catalyston the support as electrode. It is important for the support to possess a high surface area, uniform poresize, and good conductivity properties. Graphene oxide (GO) is a newly developed 2-dimension materialcontaining those excellent properties. The physical properties and structural information of the Pt/GOcatalysts were further characterized by XRD, TEM, and XPS techniques. The TEM and XRD have revealedthat the Pt/GO electrode catalyst prepared by polyol process possess a uniform dispersion and particlesize within the range of 2–3 nm. The electrocatalytic properties of Pt/GO composites and kinetic characterizationfor methanol electro-oxidation were investigated by cyclic voltammetry. In addition, thePt/GO shows better tolerance to CO for methanol electro-oxidation compared to the Pt/CNT catalyst. Theresults suggest that the Pt/GO catalyst as electrode has a good potential for application in DMFC.en_US
