Platinum Nanoparticles Supported on Reduced Graphite Oxide as Hydrogenation Catalyst

Abstract

Platinum nanoparticles supported on reduced graphite oxide are produced by reduction of a slurry including graphite oxide and H2PtCl6·xH2O, and pyridine as modifying agent. Four compounds as a formation formateion decene-1 and nitrobenzene hydrogenation at hydrogen atmospheric pressure and 45°C. In the result of reduction Pt4+ is converted to Pt metal and graphite oxide loses of oxygen. The symbasis Pt loading with C/O ratio is observed. Compositions Pt - reduced graphite oxide catalyze the hudrogenation of decene-1 and nitrobenzene in a solution. The greatest activity is shown composition reduced by sodium borohydride with the particle size of 2.0 nm, however it is substantially lower than it for Pt/fullerene black catalyst. Some inhibiton of hydrogenation by incompletely reduced graphite oxide is shown. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35054
