文摘

Modified SnO2 sensor with zeolite admixtures and overlayers (Na-A, H-ZSM-5, H-Y). Exposure to reducing gases with similar molecular structure and kinetic diameters. Great enhancements seen in zeolite-modified sensors relative to the control sensor. Gas discrimination achieved using zeolites with different properties. Zeolite admixtures were significantly better at targeting hydrocarbons selectively.
