TL;DR: The present review is concerned about the literatures published in this regard and discussions are made on the reaction mechanisms and kinetics proposed for heterogeneous CWAO and also on the typical catalyst deactivations in heterogeneousCWAO, i.e. carbonaceous deposits and metal leaching.

C. Doornkamp,Vladimir Ponec +1 more
TL;DR: In this article, the authors defined the position of this mechanism among other ways of catalytic activation, and the experimental evidence for this mechanism was presented in more detail, among them the deoxygenation of nitrocompounds and carboxylic acids.

Generation of active oxygen species on solid surfaces. Opportunity for novel oxidation technologies over zeolites
TL;DR: In this article, a new concept related to a recent discovery of remarkable ability of Fe complexes stabilized in a ZSM-5 matrix to generate a new form of surface oxygen (α-oxygen) from N2O is discussed.

The Reactions of Oxygen at Dark and Irradiated Zinc Oxide Surface
T. I. Barry,F. S. Stone +1 more
TL;DR: In this article, the results as a whole are discussed in terms of the model of zinc oxide as an n-type semiconductor with interstitial zinc, and oxygen chemisorbed as O$^-$ and O$^{2^-}$ respectively, respectively, are held to be mainly responsible for the phenomena observed.

Exchange reactions of oxygen between oxygen molecules and solid oxides
TL;DR: In this article, a theory is presented which describes the isotope exchange reactions occurring in the system containing oxygen molecules and an oxide, and the theory has been tested by the time dependences of the concentrations of O18O18, O16O18 and O16 O16 16 molecules over magnesium oxide.

Forms of oxygen bonds on the surface of oxidation catalysts
TL;DR: For oxides and metals having an equilibrium content of oxygen in the surface layer, the activity in homomolecular exchange may serve as a measure of the reactivity of the surface oxygen and is well correlated with the catalytic activity in a series of oxidation reactions as discussed by the authors.
