A series of nanoobjects of complexes with spin transition on the basis of 1,2,4-triazole and 4-amino-1,2,4-triazole in reverse emulsions was synthesized. A number of fluorescent hybrid nanocomposites was obtained by modifying the resulted nanoobjects with gold nanoparticles, pyrene-containing luminophore, quantum dots, and pyrene-containing branched polyethyleneimine. New methods were developed and N-, S- and P-containing carbon materials with acidic groups up to 2-3 mmol/g were prepared; based on these materials the active and thermally stable heterogeneous acid-base catalysts which provide a complete conversion of isopropanol to propylene at T below 200°С were obtained. Massive and supported bimetallic Ni-Co, Co-Fe and Ni-Fe catalysts of CO2 methanation were obtained. Conversion of CO2 over obtained catalysts reaches high values at 250-350°C at atmospheric pressure. The synthesized Co-Ce-Mn-oxide nanomaterials were found to be catalytically active in the CO oxidation and selective CO oxidation in the presence of H2. The conditions for obtaining platinum-containing molybdenum- and tungsten-oxide nanocomposites that are catalytically active in the CH4 oxidation have been optimized. The sensors that are highly sensitive to hydrogen at low (0.1 W) heater capacities, capable of detecting microconcentration of H2 in a wide range (from 2 to 1089 ppm), stable and fast-acting (t0.9 - 3 sec, trel - 7 sec) were synthesized on the basis of Pd / SnO2 nanomaterials. The structure of Al-Fe (Ni) -Ge, Al-PM-Si and Ca0-SiO2-Al2O3 triple systems was investigated for the first time; the determining factors in the formation of their structure were established. For the first time, the partial and integral enthalpies of mixing of melts of ternary systems Cu-Sb-Ce at 1200-1300 K and In-Mn-Gd at 1600-1650 K and the double system In-Mn in the entire concentration range at 1500-1600 K were determined.
