Environmental Pollution is a global issue. Over the last decade the demand for accurate and dedicated sensors to provide precise value of species to be monitored and control the environmental pollution have accelerated efforts for the development of new sensing material and technologies. The most important, hazardous and very common pollutant gases are CO and CO2, H2, which are produced partly by natural decays, and more by industries and other man made burning processes. SnO2, is the most extensively studied oxide while Al2O3, BaTiO3. The other oxides like ZnO, ZrO2, TiO2, MoO2, MnO3, Fe2O3,…mehr

Environmental Pollution is a global issue. Over the last decade the demand for accurate and dedicated sensors to provide precise value of species to be monitored and control the environmental pollution have accelerated efforts for the development of new sensing material and technologies. The most important, hazardous and very common pollutant gases are CO and CO2, H2, which are produced partly by natural decays, and more by industries and other man made burning processes. SnO2, is the most extensively studied oxide while Al2O3, BaTiO3. The other oxides like ZnO, ZrO2, TiO2, MoO2, MnO3, Fe2O3, etc are also reviewed in this context. SnO2, Al2O3, and BaTiO3 are sensitive to many gases but their selectivity is poor. Therefore the selectivity (to CO, H2) may be obtained by proper choice of dopants, operating temperature or some such technique like neural network. The present book gives an overview regarding development of gas sensors based on three metal semiconducting oxides SnO2, BaTiO3, Al2O3 as functional materials. This has particular emphasis on the problem of sensitivity, range and remarkable selectivity towards reducing gases mainly CO and H2.
