TLDR
In this article, the same rate equation was found empirically in the case of methanol and ethanol to ether and of tert-butanol to olefin, and the selectivity with respect to both types of compounds was regarded as a function of the thermal stability of the respective surface alkoxides.About:

Specific Poisoning and Characterization of Catalytically Active Oxide Surfaces
TL;DR: In this article, a probe molecule other than the reactant is preadsorbed as a poison and its effect on the catalytic activity studied, from the nature of interaction of this probe molecule with the surface sites one may obtain information regarding the chemical nature of these sites and from the number of poisoning molecules necessary to bring the activity to zero one may estimate an upper limit of the active site density.

Study of the acidic character of modified metal oxide surfaces using the test of isopropanol decomposition
TL;DR: In this article, the acid/base properties of a series of oxide supports (alumina, magnesia and silica) modified by increasing loadings of additive ions (Li+, Ni2+, and SO4 2 ) from 1 to 50% of the support surface coverage is reported using the catalytic test of isopropanol decomposition, studied as a function of the reaction temperature.

Kinetics and Mechanism of Ethanol Dehydration on γ-Al2O3: The Critical Role of Dimer Inhibition
TL;DR: In this article, steady state, isotopic, and chemical transient studies of ethanol dehydration on γ-alumina were conducted and it was shown unimolecular and bimolecular dehydration reactions of ethanol are reversibly inhibited by the formation of ethanol-water dimers at 488 K.

Mohamed I. Zaki,Norman Sheppard +1 more
TL;DR: An infrared spectroscopic study was made of the adsorbed species and the gas-phase products from the dehydrogenation and dehydration reactions of 2-propanol over CeO2 catalysts calcined at different temperatures as mentioned in this paper.

Nature and Estimation of Functional Groups on Solid Surfaces
H.P. Boehm,Helmut Knözinger +1 more
TL;DR: The interaction of the adsorptive with the adsorbent can very greatly in nature, i.e. from weak interaction by van der Waals forces, leading to physisorption, to strong chemical bonding or chemisorsorption as mentioned in this paper.

Infrared Study of the Adsorption of Methanol and Ethanol on Aluminum Oxide
TL;DR: The adsorbed surface species which result when aluminum oxide is exposed to methanol or ethanol vapor have been studied in this paper, where three different surface species have been identified for both methanols and ethanol.
