Stationary and Nonstationary Kinetic Studies Related to the Mechanism of Heterogeneous Catalytic Reactions

Abstract

Some results on the kinetics and mechanism of catalytic processes obtained by use of a complex strategy, including combined stationary and nonstationary investigations, are discussed. The approach developed is grounded on exact kinetic studies by gradientless methods, isotopic exchange, IR spectroscopy of surface compounds, isotopic effects, adsorption measurements, investigations of transition processes, and catalyst deactivation. The reaction kinetics is related to the specificity in the mechanism of processes under investigation.

Optimal structure and energetical relations on the catalyst surface: Evolution of concepts

“…As an example of other real simple mechanisms of six-membered ring hydrogenation on metals is a more simple 7r-complex mechanism, which demands only one active site for the reaction to proceed. Such a mechanism was proposed for aromatics hydrogenation on Group VIII metals and confirmed in our studies using a complex strategy [8][9][10][11][12][13]. T6trnyi marked the importance of the structure factors in the reaction mechanisms, however, supposed that the sextet model is now superseded [14].…”
