Abstract

Change the reduction temperature from 293 to 873 K permitted to prepare Ag-(natural clinoptilolite) samples with varying contribution of the different states of silver. At temperatures <EQ 473 K small Ag_n^m+ clusters (n < 10) and Ag_n subcolloidal particles (n approximately equals 10) are formed. Reduction at temperatures >= 573 K leads to disappearance of silver clusters and subcolloidal particles and formation of large silver particles on external zeolite surface. Prepared samples are stable in air.
