Abstract
A novel amperometric-type NO2 sensor based on La10Si5NbO27.5 (LSNO) and nano-structured NiO sensing electrode was fabricated. The nano-structured NiO particles in the range of 20-50 nm were synthesized in LSNO porous layer by the impregnating method. The sensor exhibited well response-recovery characteristics to NO2. The response current was almost linear to NO2 concentration in the range between 2 and 500 ppm at 450-600 °C. With increase of operating temperature, the sensitivity increased and reached 95 nA/ppm at 600 °C. The response current of the sensor was slightly affected by co-existant O2 and CO2 in concentration range of 0-10 vol%.
