A catalytic combustion-type carbon monoxide gas sensor was fabricated by employing a Pt-loaded cerium oxidezirconium oxidezinc oxide solid solution as the oxidizing catalyst. Since the present catalyst can completely oxidize CO at temperature as low as 25°C. As a result, the sensor with this catalyst exhibits superior performance for the CO detection at 60°C, a temperature which is substantially lower than that (>400°C) required for the operation of sensors with the conventional CO oxidation catalyst of Pt/Al 2 O 3 or Pd/Al 2 O 3 .
