Cadmium telluride nanofilms application in carbon monoxide detection
The research is centered on CdTe nanofilms. The article is aimed at developing innovative primary transducer nanoscale material for semi-conductor sensors, investigating their surface physicochemical properties and evaluation their applicability in carbon monoxide diagnostics. Cadmium telluride nanofilms were obtained by discrete thermal evaporation in vacuum. CdTe nanofilms applicability in gas analysis was investigated. Adsorption properties of the given material for carbon oxide (II) and oxygen were studied by the piezoquartz microweighing. The principles of adsorption, depending on the process conditions and the test sample habitus, were established. Based on the obtained experimental data, CO micro-impurities sensors were developed, the laboratory tests passed successfully.
Specific features and the mechanism of the adsorption of carbon monoxide on the surface of films prepared from solid solutions and the binary components of the InSb-ZnSe system
The adsorption properties of solid solutions and the binary compounds of the InSb-ZnSe system with respect to CO were studied and compared. The results were analyzed based on the known acid-base characteristics and other physicochemical properties of the adsorbents. A comparison of the adsorption properties of the binary compounds (InSb and ZnSe) and their solid solutions ((InSb) x (ZnSe) 1 - x ) revealed common features and distinctions. How the mechanism and regularities of the adsorption processes change with the composition and the experimental conditions was examined.
