ETHANOL GAS SENSING PROPERTIES OF NANOSTRUCTURED ZINC OXIDE (ZnO)

Dr. Mahendra Kumar

Abstract :

 Metal oxide semiconductors are extensively used as potential materials for the development of sensing devices for toxic and inflammable gases and vapours. The change in resistivity of active material is exploited as a sensing parameter. The invention of nanostructure materials has given a new dimension to the sensor research. Characterization and sensing response of zinc oxide nanostructure powder towards ethanol has been reported in this paper. Zinc oxide powder has been synthesized as nanoparticles by following a chemical route, starting with a solution of 0.1 M zinc nitrate in distilled water, adding ammonium hydroxide drop wise at room temperature with continuous stirring to yield precipitates of zinc hydroxide. These precipitates were dried into powder at 1200 and powder thus obtained was claimed in air at 500 0 for three hours. Synthesized zinc oxide powder was deposited as a thick film to act as a gas sensors and response to ethanol was investigated at different temperatures
