Can I read CO oxidation on planar Au/TiO2 model catalysts: Deactivation and the influence of water on EtoBox?
CO oxidation on planar Au/TiO2 model catalysts: Deactivation and the influence of water by T. Diemant; J. Bansmann; R.J. Behm is a Engineering article available to read on EtoBox.
What is CO oxidation on planar Au/TiO2 model catalysts: Deactivation and the influence of water about?
The CO oxidation behaviour of planar Au/TiO 2 model catalysts was studied by a combination of kinetic measurements and in-situ IR measurements under realistic pressure and temperature conditions (p 1⁄4 20 mbar, T 1⁄4 80 C). During reaction in a CO/O 2 mixture, the model catalysts deactivated significantly. Adding small amounts of H 2 O (1000 ppm) to the reactive CO/O 2 gas mixture, the catalyst activity increased markedly, by at least one order of magnitude. Furthermore, in-situ IR measurements show a decrease of the amount of adsorbed by-products of the CO oxidation, and a change of the predominant by-product from surface carbonate to surface formate. Possible reasons for the deactivation are discussed and the effect of H 2 O addition is compared to results of similar studies on more realistic dispersed catalysts.
