The effects of lithium oxide dopants (0.5–0.8 at. % Li) on the electrophysical and sorption properties of ZnO were studied in the temperature range from 150 °C to 410 °C. The introduction of lithium increases the activation energy of the conductivity of ZnO, decreases its conductivity, and increases the amount of S02 sorbed. Two forms of chemisorbed SO2 (donor and acceptor) are observed on the surface.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 5, pp. 1096–1100, May, 1996. 相似文献

The mutual influence of SO2 and Cl2 during their consecutive chemisorption on the In2O3 surface has been investigated. It was found that SO2 is chemisorbed in the uncharged form, and the amount of chemisorption decreases as the temperature increases. The preliminary chemisorption of Cl2 results in a dramatic decrease in the amount of SO2 sorbed and in a change in the character of the bonding of SO2 with the oxide surface. When SO2 is sorbed first, the temperature of the formation of chlorides during subsequent chemisorption of Cl2 decreases.Translated fromIzvestiya Akademii Nauk.

Chemisorption of SO2 and O2 at Pt-modified SnO2 is studied by using the vacuum static method, with simultaneous recording of electrical conductivity, over the 22 to 300°C temperature range. The SnO2 surface modification results in the increasing of SO2 adsorption and weakening of the gas-surface bonding. The chemisorption enhances the samples’ electrical conductivity. The surface pretreatment with oxygen leads to the decreasing of the successive SO2 chemisorption. 相似文献

The chemical composition of the essential oil from the roots ofAngelica sylvestris L. was studied. The structure of the major component, the tricyclic hydroazulene sesquiterpene (+)-globulol, which was isolated from a natural object for the first time, was established based on X-ray diffraction analysis. 相似文献
