Mixed potential type ppb-level acetaldehyde gas sensor based on stabilized zirconia electrolyte and a NiTiO3 sensing electrode

•NiTiO3 sensing electrode was applied to fabricate YSZ-based mixed potential type sensor for sensitive detection of acetaldehyde at 575 °C.•The sensor using NiTiO3-SE calcined at 1000 ℃ exhibited the highest response value to 50 ppm acetaldehyde and low detection limit of 200 ppb.•The sensor also di...
