Titanium Based Materials for High-Temperature Gas Sensor in Harsh Environment Application

Gas selective sensors that are capable of sensing at hot-gas environment increasingly gaining importance for the monitoring combustion and thermal processes releasing NO, NO2 H2 containing hot gases temperatures exceeding 600 °C. Despite some drawbacks, TiO2 is operating as a gas sensor above 500 In this context, Ni-doped TiO2, Co-doped Rh-doped BaTiO3 have been prepared by oxalate coprecipitation route fully characterized. Co-doping promotes p-type behavior exhibiting good properties to while Ni-doping displays maintenance n-type better H2-sensing shows excellent NO 900
