Infrared study of adsorption on oxygen-covered α-Fe2O3: bands due to adsorbed oxygen and their modification by co-adsorbed hydrogen or water

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1982
α-Fe2O3 heated in oxygen for one hour at 400 °C exhibits two complex regions of infrared absorption between 1350 and 1250 cm–1(the type A bands at 1350, 1325, 1300 and 1270 cm–1) and between 1100 and 900 cm–1(the type B bands at 1090, 1060, 1035, 1010, 990 and 930 cm–1).

Catalytic Inhibition by Adsorbed Oxygen

Nature, 1970
THE effects of adsorbed oxygen on the properties of an initially clean tungsten surface have been investigated in detail by a wide range of experimental techniques. The changes in both the field emission microscope and the field ion microscope images of tungsten tips have been reported1,2, as have the changes in the low energy electron diffraction ...

CO-oxidation model with superlattice ordering of adsorbed oxygen. I. Steady-state bifurcations

Journal of Chemical Physics, 1999
We analyze a model for CO oxidation on surfaces which incorporates both rapid diffusion of adsorbed CO, and superlattice ordering of adsorbed immobile oxygen on a square lattice of adsorption sites.

Reaction of Hydrogen with Oxygen Adsorbed on a Platinum Catalyst

Science, 1964
The release of hydrogen atoms by a platinum surface in contact with molecular hydrogen occurs if there is oxygen in the system. In particular, it is sufficient that the oxygen be adsorbed at the surface of the metal.

Oxygen adsorbed on oxidized Ru(0001)

Physical Review B, 1999
An atomic oxygen species adsorbed on Ru(0001) containing subsurface oxygen has been found and is characterized by the means of thermal description spectroscopy (TDS), ultraviolet photoemission spectroscopy, and reactive CO scattering. The surplus oxygen can be adsorbed on an oxygen-rich ruthenium crystal at room temperature when more than two ...

Magnetism of adsorbed oxygen at low coverage

Physical Review B, 2003
We report the magnetic measurement for oxygen adsorbed on different substrates at low coverage. An intriguing behavior of the oxygen magnetization against the applied magnetic field has been found. We demonstrate that it is an interplay between the substrate orientation of oxygen molecules and a weak antiferromagnetism of unit spins occurring via the ...

Cathodic reduction of adsorbed oxygen on platinum

Electrochimica Acta, 1971
Abstract The electrolytic stripping technique has been found useful to study adsorption phenomena occurring at the metal/gas interface. The method has previously been applied to the platinum-nitrogen system 1 and has now been applied to the platinum-oxygen system.

Adsorbents for chromatography of oxygen-containing compounds

Journal of Chromatography A, 1986
Abstract Adsorbents for chromatography of oxygen-containing compounds were obtained by modification of thermal carbon blacks with aromatic di- and tricarboxylic acids. The acids were applied both directly to the carbon black surface and to the surface of carbon blacks prelayered with heat-resistant polymers.

ESR of Adsorbed Oxygen Species

Catalysis Reviews, 1974
Abstract Although the catalytic oxidation of inorganic molecules, as well as the oxidation and oxidative dehydrogenation of hydrocarbons, has been the subject of extensive research, the role of oxygen in surface reactions remains uncertain. Various forms of adsorbed oxygen have been proposed on the basis of kinetic and adsorption data or electrical ...
