ABSTRACT

Zeolite is a gas sensing material. The micro pores of H-ZSM5 and H-Beta zeolites are modified with the transition metal Vanadium Pentaoxide (V2O5) by ion exchange method. The modified samples Vanadium ZSM5 (V-ZSM5) and Vanadium Beta (V-Beta) are characterized by XRD, IR and TG-DTA techniques. Systematic evaluation of gas sensing characteristics of V-ZSM5 and V-Beta zeolite has been carried for LPG gas. The gas sensing properties of these samples are studied in a static gas characterization system. The maximum Percent sensitivity factor of V-ZSM5 and V-Beta obtained for LPG gas are reported. The V-ZSM5 zeolite is found to be more suitable to LPG gas sensing
