Carbon monoxide is one of the most important reducing gases to be detected in
combustion of hydrocarbon fuel, petroleum and automobile industries, heat treating
furnaces and also in the first stages of fire. Given its toxicity both in the event of short-
term and long-term exposure, its continuous monitoring and quantification are of prime
importance. Here, we report the development of fast-responding ceramic oxide-based
chemical sensors for CO. These sensors have been realized by proper chemical variation
and tailoring the morphological features of molybdena, tungsta and titania thick films via
an innovative redox scheme. The chemiresistor sensors were made on an alumina
