The reaction on the Pt/SBA-15 was ~2 times faster (0.073 molecules·site-1·s-1) compared to Pt/MCF-17 (0.042 molecules·site-1·s-1) and Pt/SF (0.040 molecules·site-1·s-1) at 300 °C. In the case of Pt/SF, selectivity towards acetaldehyde was ~2 times higher compared to the Pt/MCF-17 and Pt/SBA-15 catalysts. In the case of Pt/MCF-17 and Pt/SBA-15, the methane to acetaldehyde ratio was ~ 4 times higher compared to the Pt/SF catalyst. The ethene selectivity was ~1.5 times higher in the case of Pt/SBA-15 compared to Pt/MCF-17 and Pt/SF. Small Angle X-ray Scattering (SAXS) studies showed striking differences in the nature of the surface of the different silica supports, which may be responsible for the activation, and selectivity deviation in ethanol decomposition reactions. The SBA-15 has the most disordered mesostructure and SF has a fine surface structure with a diffuse phase boundary may resulted in the high activity and varying selectivity, respectively.

Low-temperature (373?423 K) reduction of Rh without agglomeration is demonstrated. An average particle size of 2.3 ± 1.1 nm was measured by HRTEM regardless of the metal loading (1?5%). On Rh/CeO2, a significant particle size increase of the Rh particles was detected on heating (773 K). In this work, we suggest that the temperature-induced surface decrease resulting from the sintering of Rh is favored only for well-dispersed particles. XP spectra revealed that the mobile oxygens of CeO2 fundamentally determine the oxidation state of the supported metals. At elevated temperature, the oxidation of the reduced support surface as well as the metal component takes place because of the segregation of ceria oxygens. When the aggregated particles were reoxidized, the redispersion of Rh was observed probably because of the formation of Rh?O?Ce bonds. LA - English DB - MTMT ER -
