The purpose of the study: the creation of new functional metal-containing composites and nanomaterials for gas sensors, catalysis of transformations of small molecules and molecular switching. Research methods: SEM, TEM, RFES, 19Fss-NMR, magnetometry, optical microscopy, differential binding calorimetry, TGA, DTA, TPDMS, X-ray diffraction, X-ray fluorescence analysis, IR spectroscopy, electrophysical method of research of sensor characteristics, sensors, Correlations were made between the method of production, morphology and spin transition characteristics of materials based on iron (II) complexes with triazolate ligands. It is concluded that the cooperative effect complexes are preserved in nanoobjects. A number of new highly efficient approaches to the production of thermochromic materials based on iron (II) complexes with triazolate ligands have been proposed. Fluorination of the surface of carbon materials Freons with varying temperature, nature of carbon material and processing time obtained thermally stable fluorine-containing materials. The relationship between structure, component ratio, and physicochemical relationships has been established properties of catalysts of the process of reduction of CO2 to methane deposited on highly dispersed nonporous silicon dioxide Ni Co. It is shown that the obtained catalysts are highly active and selective in the process of CO2 conversion to methane. Highly sensitive, high-speed adsorption-semiconductor cerium-containing sensors capable of measuring very low hydrogen concentrations (<50 ppm H2) have been developed.  Product Description popup.authors Iskanderov Turhanbai С Ishchenko Olena V.
