Supported Platinum Catalysts

Graphene oxide (GO), reduced graphene oxide by thermal treatment (rGO-TT), nitrogen-modified rGO (N-rGO), and carbon Vulcan were synthesized and employed in the current work as catalyst support for Pt nanoparticles, to study their properties and impact toward the methanol oxidation reaction (MOR) in sulfuric acid medium. Several physicochemical techniques, such as X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD), Transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), Raman, and elemental analysis were employed to characterize the novel materials, while potentiodynamic and potentiostatic methods were used to study catalytic performance toward the methanol oxidation reaction in acidic medium. The main results indicate a high influence of the support on the surface electronic state of the catalyst, and consequently the catalytic performance toward the MOR is modified. Accordingly, Pt/N-rGO and Pt/rGO-TT show the lowest and the highest catalytic performance toward the MOR, respectively.

Growth Method

Controlling the morphology of platinum (Pt)-based nanomaterials is an effective strategy to enhance their catalytic performance for a given reaction. Here we report the syntheses of bimetallic Au-Pt nanomaterials with spherical or dendritic morphologies by a seed-mediated growth method. In this route, the gold (Au) nanoparticles are firstly prepared as seeds in oleylamine, which are subsequently seeded the growth of regular or dendritic Pt shells at different Au/Pt molar ratios. The electrochemical measurements show that the core-shell Au-Pt nanodendrites have better catalytic activity than that of core-shell Au-Pt nanoparticles for methanol oxidation reaction due to their abundant atomic steps, edges, and corner atoms in the branched Pt shells.
