TL;DR: In this paper, it was found that the catalytic activity of Pt for CO oxidation can be markedly and reversibly affected by depositing polycrystalline Pt films on ff'-Al203, a Na + conductor, and applying external potentials to supply or remove Na to or from the Pt catalyst surface.

TL;DR: Two quinoxaline-based propanones were tested as inhibitors of mild steel corrosion in 1 M HCl and adsorbed film of the inhibitor molecules protected the steel from direct exposure to acidic ions, suggesting higher corrosion inhibition efficiency of Mt-3-PZPP compared to Cl-4-PQPP.

TL;DR: In this article, infrared spectroscopy is applied to map pathways in the electrocatalytic oxidation of ethanol at platinum electrodes, and strong vibrational bands from adsorbed acetic acid are detected during ethanol oxidation for the first time, and the appearance of these features correlates with a region of reaction inhibition in voltammetry.

TL;DR: In this paper, the electronic structure of the new phase was identified as being characteristic of an olefinic C2H2 surface species, the result of rehybridization of the initially chemisorbed molecule.

TL;DR: In this article, a lattice-gas model using a combination of time-dependent Monte Carlo simulations and deterministic rate equations is presented for pre-cursor-mediated molecular chemisorption and thermal desorption.
Abstract: Precursor-mediated molecular chemisorption and thermal desorption are examined by means of a lattice-gas model using a combination of time-dependent Monte Carlo simulations and deterministic rate equations. Lateral interactions between coadsorbates are assumed to be both pairwise additive and limited in range to nearest and next-nearest neighbors. The interrelationships among kinetics, energetics, and adsorbate overlayer structures are analyzed in detail. The method is applied to the interaction of molecular nitrogen with the Ru(001) surface.
