A quantitative approach to calculating the energetic heterogeneity of solid surfaces from the analysis of TPD peaks: comparison of the results obtained using the absolute rate theory and the statistical rate theory of interfacial transport

Article Abstract:

A comparison is presented of the quantitative approach to calculating the energetic heterogeneity of silica-supported nickel catalysts using an analysis of temperature-programmed desorption peaks and results obtained using the absolute rate theory and the statistical rate theory of interfacial transport.

Kinetics of gas adsorption in activated carbons, studied by applying the statistical rate theory of interfacial transport

Article Abstract:

The Statistical Rate Theory of Interfacial Transport (SRTIT) is applied to predict the features of adsorption kinetics from the behavior the systems at equilibrium are presented. The essential features of sorption kinetic were found to be deduced from the behavior of an adsorption system at equilibrium.

Kinetics of isothermal gas adsorption of heterogeneous solid surfaces: Equations based on generalization of the statistical rate theory of interfacial transport

Article Abstract:

Two generalizations of the statistical rate theory (SRT) approach were developed for the kinetics of adsorption/desorption on/from heterogeneous surfaces and then compared to each other. The results showed that the square-root dependence on time of adsorption at small initial coverages could not be treated as a definite proof for that sorption proceeds through surface diffusion.
