Abstract

Clusters of CdS were prepared inside the framework voids of zeolites NaX and chabazite by multistage ion exchange chemical reaction. It was observed that each stage of reaction affects the structure of zeolites crystals. Aluminum atoms change their coordination state at the first stage because of hydrolytic decomposition of some Al-O tetrahedral bonds. Partially reversible relaxation of aluminum atoms of zeolite framework occurs during the second stage of chemical reaction. This spontaneous transition of the coordination number of aluminum atoms took place without changing of their positions of framework atoms. Such kind of the interaction between framework atoms of alumosilicates and doping ions, which are precursors of the clusters in the zeolite hosts, give indirect information about mechanism of the `ship-in-the-bottle' synthesis of semiconductor materials.
