An InSitu XAS Study of the Structural Changes in a CuOCeO2/Al2O3 Catalyst during Total Oxidation of Propane AIP Conf. Proc. 882, 693 (2007); 10.1063/1.2644635 Small-volume, ultrahigh-vacuum-compatible high-pressure reaction cell for combined kinetic and in situ IR spectroscopic measurements on planar model catalysts Rev.

Most of adsorbed ethanol is found in the form of ethoxides ͑ O-C at 1045 and 1096 cm Ϫ1 ͒. Heating the surface resulted in the transformation of ethoxides to carbonates ͑ COO at 1561 and 1347 cm Ϫ1 ͒ without the presence of stable acetaldehyde or formaldehyde species. By 673 K all surface species has been desorbed. The relative instability of these carbonates when compared to CeO 2 or Rh/CeO 2 indicates that Au is enhancing the rate of oxidation. Most of CO 2 formed during TPD is resulting from carbonate decomposition. Catalytic reactions showed that both CO 2 and H 2 can be formed with high yield over a wide temperature range.
