Alkali-metal-affected adsorption of molecules on metal surfaces
TL;DR: In this paper, a short review of the adsorption of alkali metals on well-defined transition metal surfaces is given and several models of the coadsorbed alkali metal-molecule complex are introduced.

Electrostatic adsorbate-adsorbate interactions: The poisoning and promotion of the molecular adsorption reaction
TL;DR: In this paper, the electrostatic interaction between two adsorbates, and in particular between an adsorbed atom and an adorbed or adsorbing molecule, is studied.

Mechanistic Aspects of the Formation of Hydrocarbons and Alcohols from CO Hydrogenation
TL;DR: In this article, it is shown that the world reserves of coal and natural gas far exceed those of oil, and this fact alone implies that the conversion of coal to transportation fuels is almost certain to become more widespread within the next 20 years.
Journal ArticleDOI
Microscopic model for the poisoning and promotion of adsorption rates by electronegative and electropositive atoms
TL;DR: In this paper, a theoretical framework for comparing binding energies and activation energies for adsorption on surfaces based on the effective medium theory is presented, which is applied to a microscopic description of the mechanisms underlying the promotion and poisoning of the molecular adaption process on metal surfaces by co-adsorbed species.

Thermal desorption of gases
TL;DR: In this paper, the activation energy, rate constant and order of reaction from flash-filament desorption experiments were examined, and two heating schedules were considered: a linear variation of sample temperature with time (T = T 0+st), and a reciprocal temperature variation (1 T = 1 T 0 −αt).

The effects of carbon, oxygen, sulfur and potassium adlayers on CO and H2 adsorption on Fe(100)
TL;DR: In this paper, the adsorption and desorption of CO and hydrogen was studied on clean Fe(100) and Fe (100) with adiayers of carbon, oxygen, sulfur, and potassium using X-ray photoelectron spectroscopy (XPS) using XPS, and the activation energy for dissociation was estimated to be 105 kJ/mole.

Adsorption of CO on a Ni(111) surface
TL;DR: In this article, carbon monoxide adsorbed on Ni(111) forms around θ = 1/3 an ordered √3 × √ 3/R 30c structure whose unit cell is continuously compressed upon further increasing the coverage until at saturation (θ=0.53 corresponding to 1 × 1015 molecules/cm2) a densely packed layer is reached.

TL;DR: In this article, the effect of preadsorbed electronegative atoms Cl, S and P on the adsorption-desorption behavior of CO and H2 on Ni(100) has been studied using thermal desorption, LEED and AES.
