Comparative Study of Conductivity based Silver Modified ZSM5 & Beta Zeolites as a LPG and CO2 Gas Sensor

A. A. Joshi, R. R. Attarde


Abstract: Zeolites are the gas sensing materials. The microspores of H-Zeolite Socony Mobil-Five (H-ZSM5) and H-Beta zeolites are modified with metal Silver Nitrate (AgNO3) by ion exchange method. The modified Silver- ZSM5 (Ag-ZSM5) and Silver-Beta (Ag-Beta) are characterized by X-Ray Diffraction (XRD), Infrared (IR) Spectroscopy, Thermo Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA), Scanning Electron Microscopy (SEM), Energy Dispersive Analysis of X-Ray (EDAX) techniques. Gas sensing characteristics of Ag-ZSM5 and Ag-Beta zeolite have been studied for Liquified Petroleum Gas (LPG) gas and Carbon dioxide (CO2) gas. The gas sensing properties of Ag-ZSM5 and Ag-Beta zeolite are studied in a static gas characterization system. Adsorption of gas molecules in zeolite changes the ionic activity, which interns changes conductivity. The maximum Percent Sensitivity Factor (PSF) is measured as a function of operating temperature and as a function of gas concentration for LPG and CO2 gas.
