The catalytic properties of the initial oxidising samples were studied in a gas phase isopropanol dehydratation. It was determined, that the bimetallic systems based on (Pt-Pd) and (Pd-Ag), supported on SnO2 show higher catalytic activity than the individual metals in reactions of СН4, CO and Н2 oxidation. The CO oxidation on oxide Fe-Mn, Cu-Co-Fe catalysts was investigated.Catalytic activity of massive and supported on SiO2 binuclear copper (II) complexes with acyldihydrazons of trifluoracetylacetone was investigated for CO oxidation. A proposed mathematic equation in a view of heterogeneous catalytic mechanism of the sensor's sensitivity was found to be in a good agreement with dependence of the sensor conductivity versus the CH4 concentration at differenttemperatures.
