Notes: Abstract The influence of halide ions on the state of dispersed Pt in oxidized catalysts has been investigated, adsorbed CO being used as a probe. Charged platinum complexes form upon catalyst oxygenation, with CO bands at 2130, 2150, 2165, 2170 and 2180 cm−1. Composition of the complexes depends on the oxidation temperature and the nature of the halide ion.

Notes: Abstract The vibrational and vibrational–rotational spectra of hydrogen adsorbed on zeolite BaX at 77 K were examined by diffuse-reflectance IR spectroscopy over a wide range of wavenumbers. The use of hydrogen enriched in the para isomer and of molecular deuterium allowed us to reliably assign the absorption bands to orthohydrogen and para-hydrogen and compare the experimentally observed band splitting with the theoretically calculated shifts of the corresponding levels resulted from the Stark effect. In the calculations, an adsorption site was simulated as a positive point charge. Although this approximation is rough, the IR spectra of adsorbed hydrogen and deuterium are adequately described in terms of the Stark effect. A decrease in the frequency of stretching vibrations of H–H (D–D) bonds in the molecules coordinated to Ba2+ cations, a decrease in the intensity of vibrational–rotational absorption bands, and the band splitting in the spectra of adsorbed para-hydrogen and orthohydrogen were explained.

Notes: Conclusions 1. When alumina-Iron catalysts obtained by decomposition of polynuclear iron carbonyls are promoted by the addition of potassium, the relative amount of reduced metallic iron is increased, and this correlates with their catalytic activity in the Fischer-Tropsch reaction. 2. Oxidized forms of iron do not manifest any activity in this reaction. 3. Nitric oxide cannot serve as a test for surface states of iron in these systems.
