Object of study: the processes of obtaining and forming new nano- and composite materials with optimal properties based on metals, oxide and coordination compounds, carbon materials and their functional efficiency as sensors, catalysts, molecular switches, superfluous materials and electrochemical elements. Aim of the study: creation of new functional metal-containing composites and nanomaterials for gas sensing, catalysis of small molecule transformations and molecular switching. Research methods: HA, SEM, TEM, RFES, NMR, magnetometry, optical microscopy, differential binding calorimetry, TGA, DTA, TPDMS, RFA, X-ray fluorescence analysis, IR spectroscopy, LCS, electrophysical method for the study of chromatography characteristics. The method of gas-phase fluoroalkylation in the temperature range of 400-800 ° C was developed using 1,1,1,2-tetrafluoroethane or pentafluoroethane and a new type of thermally stable fluorine-containing carbon materials with a fluorine content up to 2-3 mmol / g was obtained. An alternative approach to the preparation of complex compounds with SP by the method of direct synthesis was developed and complexes of ferum (II) with 1,2,4-triazole derivatives were synthesized. Optimal conditions for synthesis of metallic Co-Ni-Fe massive and Ni (Co) -Fe deposited on carbon carriers with different surface morphology were determined. The method of solvated stimulated modification of silica surface by metal salts for the preparation of Ni (Co) / SiO2 oxide precursors to metal methane catalysts for CO2 methane was developed. New cerium-containing nanoscale semiconductor gas-sensitive materials were obtained using sol-gel technology and high-speed adsorption-semiconductor sensors were created based on them. The most sensitive sensors based on Ce / SnO2-Sb2O5 were obtained in two concentration ranges of cerium chloride (0.4–0.6 10-2M and 1 10-2M).
