| 英文摘要 | Preferential oxidation (PROX) reaction of CO in H-2 catalyzed by a new catalyst of FeOx /Pt/TiO2 (Fe: Pt: TiO2 = 100: 1: 100) was studied by dynamic in-situ DRIFT-IR spectroscopy. The oxidation of CO is markedly enhanced by H-2 and H2O, and the enhancement by H-2/D-2 and H2O/D2O takes a common hydrogen isotope. Dynamics of DRIFT-IR spectroscopy suggests that the oxidation of CO with O-2 in the absence of H-2 proceeds via bicarbonate intermediate. In contrast, rapid oxidation of CO in the presence of H-2 proceeds via HCOO intermediate and the subsequent oxidation of HCOO by the reaction with OH, that is, CO + OH -> HCOO and HCOO + OH -> CO2 + H2O. The latter reaction is a rate determining step being responsible for a common hydrogen isotope effect by H-2/D-2 and H2O/D2O. |
