Natural clinoptilolite (N-CLI) is a polyphase mineral containing
clinoptilolite, -quartz, mordenite, and hematite at certain ratios. We use
clinoptilolite in its acid-modified forms (H-CLIs) as a support for Pd(II)-Cu(II)
complexes (Pd-Cu/Н-CLIs) characterized by catalytic properties in the reaction
of CO oxidation. N-CLI used in the study was provided from Sokirnitskoye
deposit (Trans-Carpathian region). (0.25-3)Н-CLI-0.5H-CLI samples were
prepared by N-CLI boiling for 0.5 h in nitric acid solution at its concentrations
ranged from 0.25 to 3 M. Since water molecules directly participate in the
formation of Pd(II)-Cu(II) surface complexes, we investigated ad/desorption of
water vapor into/from N-CLI, (0.25-3)Н-CLI-0.5, and Pd-Cu/Н-CLIs using
well-known McBain gravimetric method.
