NO2 sensing properties of electrode-supported sensor by tape casting and co-firing method

Potentiometric NO2 Sensors Based on Thin Stabilized Zirconia Electrolytes and Asymmetric (La0.8Sr0.2)0.95MnO3 Electrodes

“…The calculated crystallite size using the Scherer formula is about 83.7 nm. Chemical compatibility between LSM95 and 8YSZ was confirmed by X-ray diffraction patterns of their composites calcined at 1150–1350 °C, where no additional peaks from impurities were observed [26]. Figure 4 shows the SEM micrograph of carbon which was used as pore former in the thick LSM95 layers and the particles are spherical granules.…”

“…Recently, we have shown that the LSM95-supported NO sensors are based on a mixed-potential model [26]. Compared with previously reported YSZ-based NO x sensors [6,28,29], the reference and sensing electrodes of S-15LSM95 are largely the same in terms of chemical composition and microstructure, but had very different thicknesses, which may play a critical role in determining the sensing performance.…”

Impedancemetric NO x Sensors Based on LSM and LSM-Au Sensing Electrodes

“…The perovskite, strontium-doped lanthanum manganite, La0.8Sr0.2MnO3 -LSM is an attractive alternative to Au from a manufacturing perspective as tolerates the high firing processing steps for accompanying sensor components and its thermal expansion coefficient is more compatible with YSZ. In addition, LSM has demonstrated low cross-sensitivity to interfering gases, such as NH3, CO and hydrocarbons (2,4,5). Yet, managing water crosssensitivity remains challenging for LSM based sensors (2).…”
