Description
Summary:Nanometer-sized materials, which have high surface activity due to their small particle size and enormous surface area, have been widely studied in the field of gas sensors in recent years. The samples were obtained by self-combustion method and were studied using powder X-ray diffraction and scanning electron microscopy. It was investigated the sensitivity of the electrical resistivity to acetone, ethanol, methane (CH4) and liquefied pertroleum gas (LPG). It is observed that the gas sensitivity depends on the temperature and the test gases to be detected.
