TL;DR: In this paper, a flow gravimetric technique was used to measure oxygen chemisorption on the sulfided catalysts of a catalytic microreacter at atmospheric pressure.

TL;DR: In this article, a series of silica and alumina-supported Pt catalysts of widely varying mean particle size was studied and a correlation of the oxidation extent (as measured by temperature-programmed reduction) with mean particle radius (as determined from chemisorption measurements) was determined.

TL;DR: In this paper, the main concepts for chemisorptive particle emission are reviewed, as is its application for the recording of reaction kinetics and finally the information that it can provide on the dynamics of charge-transfer reactions at surfaces is examined.

TL;DR: In this paper, infrared spectroscopy was used to obtain absolute number information on the reaction products during atomic layer deposition of Pt from (methylcyclopentadienyl)trimethylplatinum [(MeCp)PtMe3] and O2.
Abstract: Infrared spectroscopy was used to obtain absolute number information on the reaction products during atomic layer deposition of Pt from (methylcyclopentadienyl)trimethylplatinum [(MeCp)PtMe3] and O2. From the detection of CO2 and H2O it was established that the precursor ligands are oxidatively decomposed during the O2 pulse mainly. Oxygen atoms chemisorbed at the Pt lead to likewise ligand oxidation during the (MeCp)PtMe3 pulse however the detection of a virtually equivalent density of CO2 and CH4 also reveals a concurrent ligand liberation reaction. The surface coverage of chemisorbed oxygen atoms found is consistent with the saturation coverage reported in surface science studies.

TL;DR: In this article, a model based on the effective medium theory of the oxygen-induced reconstruction of the (110) and (100) surfaces of Cu is presented, and equilibrium structures are calculated from a minimization of the total energy of the system.
Abstract: A model calculation based on the effective-medium theory of the oxygen-induced reconstruction of the (110) and (100) surfaces of Cu is presented. Equilibrium structures are calculated from a minimization of the total energy of the system. Missing-row-type reconstructions are found to be most stable in both cases, and an analysis is presented, showing what the driving force is behind these reconstructions.
