This paper compares two TiO 2 thick film gas sensors to the hydrogen at elevated operating temperatures. The first gas sensor was prepared by applying nitrogen treatment at 200 °C for 2 h to the TiO 2 powder before the TiO 2 paste was prepared. The second gas sensor was prepared using TiO 2 powder w...
