Реферат:
A dual-site mechanism of H2 dissociation on the Pd particles and then migration Hads across the TiOx surface to the active sites with the O2δ-ads species have been studied on the defects of Ti3 +-O/TiO2 and Pd-Ti3 +-O/TiO2 types with XPS, UPS, TDS, mass-spectrometry and pre-adsorbed oxygen photodesorption techniques. The effect of spillover phenomena (Hads/Pd → O2ads/Ti3 +/TiO2) on the overall rate of H2 oxidation have been studied as well. The role of defects (Ti3 + sites) in the adsorption centres formation, their stabilization by the palladium particles and then defects participation in H2 + O2 reaction have been studied on the TiOx surface. The results obtained with H2 + Oads reaction over Pd (110) single crystal surface have been compared. A series of activity sets: Ti3 +/TiO2 << Pd ~ Pd-Ti3 +/TiO2 have been determined. Through the hydrogen spillover from Pd to Ti3 +/TiO2 H2 oxidation proceeds on two sites of the Pd- model catalysts in can occur: on Pd particles and on the Ti3 +/TiO2 support.
