Kinetics and kinetic oscillation in carbon monoxide oxidation

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1974
A kinetic mechanism is proposed for the low temperature oxidation of carbon monoxide. A general mathematical model which conserves all reactants, catalytic impurities and intermediate species is formulated to contain all proposed reactions without invoking the assumption of steady states.

Revisiting kinetics of morin oxidation: Surface kinetics analysis

Applied Surface Science, 2017
Abstract Herein we report on the kinetics aspect of morin oxidation. This is described by the use of the Langmuir-Hinshelwood and modified Mars-van Krevelen kinetic models. The Langmuir-Hinshelwood kinetics model enabled the determination of adsorption constants of morin and peroxide on the surface of the catalyst, K morin and K H 2 ...

Kinetics of the thermal oxidation of polydimethylphenylene oxide

Polymer Science U.S.S.R., 1982
Abstract The high-temperature oxidation of poly-2,6-dimethyl-1,4-phenylene oxide has been investigated in the temperature range 230–270° under oxygen pressures up to 2 × 10 4 Pa. The oxidation takes place in accordance with an autocatalytic law, which is accounted for by the accumulation of readily oxidizable aldehyde groups.

Kinetics of oxidative precipitation of iron oxide particles

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract Conditions for the formation of Fe3O4, α- and γ-FeOOH by the oxidation of Fe(OH)2 have been studied. In a system containing Fe(OH)2(s), Fe2O3·χH2O and excess Fe(II)(aq), the evolution to δ-FeOOH, Fe3O4, green rust, α-FeOOH or γ-FeOOH depends on the kinetics regime, controlled principally by the oxidation rate, initial ratio R0 = [Fe2+]0/[OH−]

Alkali metal promoted oxidation of semiconductors: oxidation kinetics

Vacuum, 1990
We have studied the oxidation of alkali metal covered semiconductor surfaces, in particular the system Rb/Si(100)2 × 1, by core level photoelectron spectroscopy, monitoring the growth of oxide as a function of alkali metal coverage and oxygen exposure.

Dynamic kinetics of CO oxidation over magnesium oxide

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1987
The dynamic kinetics of CO oxidation on magnesium oxide have been studied using the transient response method due to the concentration jump and temperature jump techniques at temperatures in the range 150–171 °C. Two different types of absorbed CO2, strongly and weakly adsorbed, were recognized on the surface during the reaction.

Kinetics of oxidation in oxide ceramic matrix composites

Materials Science and Engineering: A, 2003
Abstract Oxidation of SiC reinforcement is a major factor affecting the environmental stability of SiC reinforced ceramic matrix composites (CMCs) for high temperature applications. A new quantitative model for the oxidation of oxide CMCs with non-oxide reinforcements is described.

Kinetics of Oxidative Decarboxylases

1984
A common approach to understanding enzymic catalysis is to dissect the overall reaction into likely steps and study the kinetics of each of them in isolation by fast reaction techniques.

Enzyme Kinetics of Oxidative Metabolism—Cytochromes P450

2014
The cytochrome P450 enzymes (CYPs) are the most important enzymes in the oxidative metabolism of hydrophobic drugs and other foreign compounds (xenobiotics). The versatility of these enzymes results in some unusual kinetic properties, stemming from the simultaneous interaction of multiple substrates with the CYP active site.
