Реферат:
In the study of the mechanism of catalytic redox reactions, the investigation of the nature of the interaction of oxygen with the catalyst surface is of considerable importance. In the present work, infrared spectroscopy was used to study the influence of treatment of the oxides MnO2, Fe2O3, and Cr2O3 with oxygen on their surface properties. Several forms of adsorbed oxygen are produced by the dissociative chemosorption of oxygen on the oxides studied. The absorption bands corresponding to the different forms of adsorbed oxygen lie in the spectral range of the stretching vibrations of the surface cation-oxygen bonds, which vary from single bonds to double bonds. There is a difference in the thermal and chemical stabilities of the forms of adsorbed oxygen detected. The adsorption maxima produced by the adsorption of of oxygen on the oxides are related to the presence, on the surface, of cations with different degrees of coordination saturation with respect to oxygen. The forms of adsorbed oxygen with the greatest thermal stability exhibit the greatest reactivity with respect to the addition of molecules of water, ethanol, CO, and CO2.
