Thin film gas sensors made of the MWCNTs•Fe2O3 (1:25) nanocomposite material with different structure of ohmic contacts were manufactured using the electron–beam spattering method. Investigations of the response of prepared sensors to such gases as methane, butane, hydrogen and ethanol vapors were carried out. It was established that sensors show significant response to hydrogen and ethanol vapors at relatively low temperatures of the working body. It was also established that the structure of ohmic contacts highly effects on sensors characteristics: sensors with different structure of ohmic contacts can be used as highly selective sensors for detection of small concentrations of ethanol vapors and hydrogen gas.
