The project aims to develop methods of detecting hazardous products in the air based on the technology of combining semiconductor detectors with preconcentration of target molecules on molecular sieves . Methods have been developed and synthesized nanocrystalline semiconducting metal oxides , are chemically modified catalytic clusters having selectivity to organophosphorus and nitrogen - containing molecules. Synthesis of nanocrystalline oxides SnO2, In2O3, ZnO with a crystallite size controlled in the range of 3-20 nm performed by chemical vapor deposition from colloidal solutions . Catalytic clusters Au, PtO2, PdO, RuO2, CuO, NiO supported on the surface of the semiconductor matrix during synthesis or nanocrystalline oxide by an impregnation method . For selective concentration of target gases complex synthesized mesoporous aluminosilicates ( zeolite analogues ) with different pore structure with a system of controlled pore diameter from 30 A to 5.5 A. The properties of the materials of sensor measurements are carried out on the bench for a fully automated detection of H2S and NH3. As used organophosphorus desired product dimethylmethylphosphonate (DMMP), a nitrogen-containing substance used as unsymmetrical dimethylhydrazine (UDMH) .
