Selective Detection of Nitrogen Monoxide by the Mixed Oxide of Cr2O3–Nb2O5

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.
