The methods of modification of carbon nanomaterials with O-, Hal-, N- and S-containing functional groups were developed and it was shown that the use of Hal-containing precursors increases the effectiveness of the introduction of N- and S-containing groups into the surface layer, that allows to obtain materials with predetermined properties. The micro-heterogeneous structure of the glass melt system Na2O-SiO2 and the nature of ordering of atoms in melts Al-Ge(Si), Ni-Si, Al-Co(Fe, Ni, Mn)-Si, Al-Mn-Co(Ni), Al-Co(Fe, Ni)-Ge and amorphous-crystalline films based on them were found out. The thermochemical properties of melt of Al-Ni (Co), Co-Ce (Sb), Ce-Sb, Fe-Pr (Nd, Ce, Sb), Al-Co (Ni) -Si, Co (Fe) -Ce- Sb were studied and their correlation with the structure of the corresponding melts and electronic structure of the components was determined. The investigation of bimetallic oxide systems shows that the samples (wt.%): 15Cu-85Co; 35Co-65Fe and 85Co-15Fe can be used for cleaning hydrogen-containing gas mixture of CO impurities. Se-, Ce-Co- and Mn-containing systems based on zeolites that have the advantage in cost and selectivity in comparison with Pt-catalyst for proton-exchange membrane fuel cells were synthesized. Sensor and catalytic properties of nanoscale systems Co/SnO2 were compared and possible mechanism of action of sensors was proposed. The factors that contribute to high sensitivity of 0,2% Co/SnO2 sensor to hydrogen at micro concentration were found. Product Description popup.authors Іщенко О.В. Бєда О.А. Безугла Т.Н.
