- W1566186936 abstract "Temperatures required for extensive N2O dissociation to N2, or to N2 plus O2, over 0.5% RhOx/CeO2 materials, and over polycrystalline Rh2O3 or CeO2, are compared for preoxidised and for prereduced samples on the basis of conversions achieved in pulsed-reactant, continuous-flow and recirculatory microcatalytic reactors. Influences of sample prereduction or preoxidation upon those measurements and upon results from parallel ESR and FTIR studies of N2O interactions with such materials are presented and compared. Over partially reduced 0.5% RhOx/CeO2 materials complete dissociation of N2O pulses to N2 plus O2 is obtained at temperatures 50–100° lower than those required for extensive dissociation over prereduced Rh2O3. Furthermore, N2 was the sole product from the latter. Higher ongoing N2O conversions to N2 plus O2 at 623 K over 0.5% Rh/CeO2 in pulsed-reactant than in continuous-flow mode point to regeneration of active sites under helium flushing between pulses. The TPD profile for dioxygen release from Rhodia containing samples at temperatures 350–550 K is presented. ESR measurements reveal complementary effects of outgassings at temperatures, Tv, ≥573 K upon the availability at RhOx/CeO2 surfaces of electron-excess sites reactive towards N2O. Differences from observations over Rh2O3 and CeO2 can be understood by attributing the low-temperature activity of RhOx/CeO2 to electron excess sites at microinterfaces between the dispersed Rhodia component and the Ceria support." @default.
