INTERMEDIATES AND MECHANISMS OF THE HETEROGENEOUS CATALYTIC REACTIONS - THE REACTIONS OF HYDROCARBONS, ALCOHOLS, ACIDS

Structure of the surface intermediates in the heterogeneous catalytic transformations of hydrocarbons, alcohols and acids, obtained basing on the spectral (mainly IR-spectral) investigations is studied. The catalytic roles of definite structures are arranged in accordance with the degree of trustworthiness: the lower degree - on the base of the spectra before and after catalysis, the middle degree - on the base of spectral data in situ, but without kinetic measurements, and the higher degree - on the base of spectral data in situ together with the comparison of the reaction kinetics and the kinetics of the surface compounds concentration changes. Schemes of the heterogeneous catalytic reactions mechanisms are given, proposed on the base of the information about surface complexes.
