Mechanism of catalysis and factors responsible for oxide catalyst activity in deep oxidation reactionsReaction Kinetics, Mechanisms and Catalysis - - 1988
V. D. Sokolovskii
A general scheme for the deep oxidation mechanism on oxide catalysts including stepwise and concerted mechanisms as well as their mutual transformations is suggested. The principal factor responsible for the activity in the concerted mechanism region is the rate of oxygen binding. For the stepwise mechanism the main factor is the rate of catalyst interaction with oxidizable reactant.

The liquid-phase hydrogenation of benzylideneaniline over various Pd catalysts, using gaseous hydrogen has been studied. We have synthesized several Pd catalysts (3 wt.%) over SiO2−AlPO4 and sepiolite supports, and determined their metal surface area by X-ray diffraction. The study performed shows that the process follows a Langmuir-Hinshelwood kinetics with zero order in benzylideneaniline, ri=ko...... hiện toàn bộ
Stability of cefoselis sulfate in aqueous solutionsReaction Kinetics, Mechanisms and Catalysis - Tập 108 - Trang 285-292 - 2012
Przemysław Zalewski, Judyta Cielecka-Piontek, Anna Jelińska
The influence of pH on the stability of cefoselis sulfate was investigated in the pH range 0.44–13.00. The degradation of cefoselis sulfate in aqueous solutions was a pseudo-first order reaction. General acid–base hydrolysis of cefoselis sulfate was observed in phosphate and acetate buffers. In solutions of hydrochloric acid, sodium hydroxide and borate buffer, kobs = kpH because only specific aci...... hiện toàn bộ
Hydrogen atom transfer versus proton coupled electron transfer mechanism of gallic acid with different peroxy radicalsReaction Kinetics, Mechanisms and Catalysis - Tập 123 - Trang 215-230 - 2017

Reactions of gallic acid (GA) with alkyl peroxy radicals (methylperoxy, ethylperoxy, iso-propylperoxy, and tert-butylperoxy) were simulated using density functional theory. The reaction is taking place in the way that hydrogen of hydroxy group of GA is transferred to the oxygen of each of peroxy radical. A newly formed radical is stabilized with delocalization of spin density over entire molecule,...... hiện toàn bộ
Dealumination of the outer surface of MFI zeolites by ammonium hexafluorosilicateReaction Kinetics, Mechanisms and Catalysis - Tập 54 - Trang 209-215 - 1995

The treatment of MFI zeolites with ammonium hexafluorosilicate causes a selective dealumination of their outer surface. This dealumination improves the selectivity to the para isomer of m-xylene isomerization.
Catalytic combustion of methane over La2BCoO6 perovskites containing Ni, Cu and Fe: impact of B-sites on oxygen species and catalytic activityReaction Kinetics, Mechanisms and Catalysis - Tập 131 - Trang 737-752 - 2020
H. Rezaei Shadegan, S. Maghsoodi, B. Ghanavati, A. Shahbazi Kootenaei, A. Azimi
The effect of B-site partial substitution on the structure and the catalytic performance of cobalt-based double perovskites (La2BCoO6 where B = Cu, Ni and Fe) was investigated in the catalytic combustion of methane. The synthesized samples were characterized using XRD, XRF, N2-physisorption, H2-TPR, O2-TPD, CH4-TPR and XPS techniques. The XRD results showed the successful synthesis of cobalt-based...... hiện toàn bộ
