Abstract

Catalytic and sensing properties of several metal oxides in the reaction of CO oxidation and in the sensor detection of CO in air have been studied and compared to each other. Indium oxide has been found to be the most sensitive and possessing a relatively low catalytic activity in the oxidation of CO. Possible reasons for the high activity of the indium oxide sensor matrix are discussed. The promoting effect of Au and Pd doping of In2O3in the detection of CO in air has been studied, and a mechanism explaining the enhanced sensor response of Au-doped In2O3has been proposed. A change in humidity has no significant effect on the sensor response of Au-doped In2O3in the detection of CO in air.
