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−δ. Its CO gas sensing performance was also investigated. Since the 11 wt% Pt/La9.0Si5.8Mn0.2O27−δ catalyst oxidized CO at a temperature over 60°C, the sensor also responded to CO at temperatures above 60°C, showing superior CO detection at 130°C with high sensitivity and a rapid response time of 10–20 s.
