High performance of SnO2-based gas sensor by introducing perovskite-type oxides

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Sensing layer mixed perovskite oxide, La0.1Sr0.9Co0.4Fe0.6O3-δ (LSCF), and Pd-loaded SnO2 nanoparticles (LSCF@Pd-SnO2) was deposited on the membrane of MEMS device by injection method, and its gas sensing properties to reducing gases and VOCs were investigated by heating sensor in pulse mode with heaters in ON and OFF state for one second repeatedly. The MEMS sensor showed fast response, high sensitivity and stability to 200 ppm C7H8 at 250°C by pulse heating with extremely low power consumption.
