Effects of different preparation methods on the electro-catalytic performance of Pt/Graphene

  • Pt/Gr catalysts were prepared via both organic sol method and sodium borohydride reduction method (denoted as Pt/Gr-OS and Pt/Gr-SR, respectively) with grapheme oxide (GO) as carrier precursor and chloroplatinic acid with polyvinyl pyrrolidone (PVP) as complexing agent.TEM and XRD were used to characterize the morphology, particle size, and size distribution, and the electro-catalytic performance of the catalysts for methanol oxidation was also investigated by means of cyclic voltammetry and chronoamperometry. The results showed that compared with Pt/C, the Pt/Gr catalysts obtained by using both of the methods had high dispersion and Pt/Gr-OS had higher dispersion than Pt/Gr-SR; Pt/Gr-OS had smaller particle size,larger electrochemical activity specific surface area,and higher electro-catalytic performance on methanol oxidation.The electro-catalytic performance of Pt/Gr-OS was 1.7 and 3.8 times as those of Pt/Gr-SR and Pt/C catalysts, respectively. In addition, Pt/Gr-OS had higher stability than Pt/Gr-SR and Pt/C.
