Реферат: Characteristic features of Pt/C catalysts prepared through re-ductive deposition from an aqueous solution have been inves-tigated. The carbon support was found to act as an effective nucleating agent and to ensure the formation of small and predominantly nonaggregated Pt particles, probably through a preliminary formation of oxide nuclei on the carbon surface. The deposition rates could be high enough to provide the lo-cation of Pt nanoparticles near the external surface of the sup-port and outside micropores. The depositions onto bare carbon supports and Pt/C samples presynthesized by using an-other method proved equally effective, which thus opened a route to various types of metal distribution. With the same metal precursor, reductant, and base (H2PtCl6, NaOOCH, Na2CO3), catalytic properties could be influenced through the support, Pt loading, and deposition conditions. In the oxida-tion of isopropyl alcohol as a model test reaction, alcohol con-version could be as high as 99.7% and turnover frequencies 80000 h-1 [H2O, O2, 1 bar (100 kPa), 308C].
