A novel catalytic combustion-type CO gas sensor was devised using a catalyst composed of 11 wt% Pt supported on the apatite-like Mn-doped oxide La9.0Si5.8Mn0.2O27-delta. Its CO gas sensing performance was also investigated. Since the 11 wt% Pt/La9.0Si5.8Mn0.2O27-delta catalyst oxidized CO at a temperature over 60 degrees C, the sensor also responded to CO at temperatures above 60 degrees C, showing superior CO detection at 130 degrees C with high sensitivity and a rapid response time of 10-20 s.
