Реферат:
Structural, electronic and catalytic properties of CU-O/TiO2 mixed oxide catalysts tested for CO oxidation, wich were obtained by a modified alkoxysynthesis method from Ti(OnBu)4 and Cu(Cu17H35COO)2, have been studied by X-ray diffraction, EXAFS, XPS, magnetic susceptibility techniques and kinetic measurements. Partial chelation of Ti(OnBu)4 by acetylacetone was shown to stabilise sols and to ensure anatase-based single phase CuxTi1 −.0,5x02(x ≤ 0.06).For x ≥ 0.06, the formation of cupric oxide and titania gives evidence of phase separation. At temperatures T < 150 °C, an overall CO conversion over the CuxTi1–0,5xO2 depends on the parameter x and on mean crystal size < d >: by increasing x and decreasing < d >, there is a marked increase in activity. It is suggested that terminal (non-bridged) oxygen of the bond Cu = OS, surface anion vacancy VS, related to the reduced Cu+ 1 state and surface labile species OS participate in CO oxidation. At temperatures T > 150-200°C, the participation of lattice oxygen in the reaction mechanism is postulated.
