INTERMEDIATES AND MECHANISMS OF HETEROGEN EOUS CATALYTIC REACTIONS - OXIDATIVE REACTIONS WITH MOLECULAR-OXYGEN AND SULFUR PARTICIPATION

Structure of the surface intermediates in heterogeneous catalytic reac tions obtained on the base of spectral (mainly IR-spectral) measuremen ts is studied. A gradation of trustworthiness degree of the role of de finite structures is performed: 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 high er degree - on the base of spectral data in situ together with the com parison of the reaction kinetics and the kinetics of the surface compo unds concentration changes. Schemes of heterogeneous catalytic reactio ns mechanisms on the base of the information about surface complexes a re given. Bibliography - 141 references.
