Abstract


Water vapour adsorption-desorption properties of natural clinoptilolite (N–CLI) and mordenite (N‑MOR) samples (Trans-Carpathian region, Ukraine), their acid modified forms, Н–CLI–6 and Н‑MOR‑6, and catalysts for both CO oxidation, Pd(II)-Cu(II)/Н-CLI-6 and Pd(II)-Cu(II)/Н-MOR-6, and ozone decomposition, MeCl2/N-CLI (Me = Cu, Co, Mn), have been studied. All adsorption isotherms at p/ps < 0.4 are described by BET equation with correlation coefficient R2 = 0.99. The activity of the catalysts depends on water content in samples.
