Abstract
Several single and mixed oxides were used as sensors for detection of CO, CO2, NO, and NO2. The conductivity of (Cr2O3)1-x (Nb2O5)x was greatly changed by a contact with 1-1000 ppm of NO, but was unchanged by that with CO or CO2. The sensitivity to NO was maximum by operating at 573 K using oxide with x=0.1. The influence of CO during detection of NO was negligible at x=0.5.Keywords
