Synthesis of nanocrystalline powders held SnO<sub>2</sub> a- gel deposition of tin acid followed by heat treatment . Clusters from metals Fe, Co, Ni, Pd, Au, Ru , and Cu and bimetallic clusters based on Au-Ni, Au-Fe and Au-Co. Values ​​with different metals applied to the surface of the pre -synthesized nanocrystalline SnO<sub>2</sub> by impregnation and anion adsorption. Thin films of 0.8 mm thickness of tin dioxide , chemically modified bimetallic clusters Pd-Cu were prepared by spray pyrolysis of organic compounds on insulator substrates. The systematic study of the influence of the catalyst clusters on the electrical properties of powders and films by measuring the dc conductivity and impedance spectroscopy in a wide temperature range. The contribution of ionic and electronic conductivity, surface area and volume of the crystallites depends on the nature of catalityc clusters. All measurements were performed in a controlled atmosphere.</span><br style="font-weight: normal;"> <span style="font-weight: normal;"> The effect of bimetallic clusters on sensory properties of the modified stannic oxide upon detecting trace amounts of toxic gases NO<sub>2</sub>, CO, H<sub>2</sub>S, NH<sub>3</sub>, acetone and ethanol in air. It has been shown that the catalytic clusters increases the sensor signal magnitude and reduce an operating temperature of the semiconductor sensor. Found a synergistic effect due to the mutual influence of Au and Ni clusters on the sensitivity of the material to NO<sub>2</sub>. The optimum compositions of sensor materials for the detection of NO<sub>2</sub> and CO at the maximum permissible concentration (MPC working area). <span style="font-weight: bold;">The result of the application for the invention "Method of preparation material gas sensor based on tin dioxide".</span></span></p> </td> </tr> <tr> <td class="Header" height="30"> <p class="webmaster">web-design: <a href="mailto:ddirin@rambler.ru" class="webmaster">ddirin@rambler.ru</a></p> </td> <td colspan="5" class="Header" height="30"> <p class="Contact">© 2008-2014 The Laboratory of chemistry and physics of sensor and semiconductor materials.</p> </td> </tr> </tbody> </table> </td> <td valign="top" width="*"> <table border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody> <tr> <td class="Header" height="155"> </td> </tr> <tr> <td> </td> </tr> <tr> <td> </td> </tr> </tbody> </table> </td> </tr> </tbody> </table> <hr class="line1"> <hr class="line2"> <div class="divheader"></div> </body></html>
