Metal oxide nanocomposites: Advantages and shortcomings for application in conductometric gas sensors

Abstract

The features of conductometric gas sensors based on metal oxide composites are considered. The methods of the composites forming and the advantages of their using in the development of gas sensors are discussed. It is given the analysis of the factors that reduce the effectiveness of the composites using in conductometric gas sensors, which should be taken into account while designing and fabricating sensors based on metal oxide composites. The mechanisms explaining the operation of conductometric gas sensors based on metal oxide composites are also discussed. © 2016 Trans Tech Publications, Switzerland.
