This paper compares two TiO2 thick flm gas sensors to the hydrogen at elevated operating temperatures. The frst gas sensor was prepared by applying nitrogen treatment at 200 °C for 2 h to the TiO2 powder before the TiO2 paste was prepared. The second gas sensor was prepared using TiO2 powder without...
