Gas Sensors Based on Porous Ceramic Bodies of MSnO₃ Perovskites (M = Ba, Ca, Zn): Formation and Sensing Properties towards Ethanol, Acetone, and Toluene Vapours.

ABSTRACT: In this work, the gas-sensing functionality of porous ceramic bodies formed by the slip casting technique was studied using perovskite nanoparticles of an MSnO₃ system (M = Ba, Ca, Zn) synthesized by a chemical route. The performance and reliability of the sensitive materials in the presence of different volatile organic compounds (acetone, ethanol, and toluene), and other gases (CO, H₂ and NO₂) were analysed. The ZnSnO₃, BaSnO₃, and CaSnO₃ sensors showed sensitivities of 40, 16, and 8% ppm^-1 towards acetone, ethanol, and toluene vapours, respectively. Good repeatability and selectivity were also observed for these gaseous analytes, as well as excellent stability for a period of 120 days. The shortest response tim
