Abstract

A composite material made up of AgI and the potassium form of the synthetic zeolite ZSM5 has been prepared by treating the silver form of ZSM5 with potassium iodide. The composite has been characterised by X-ray powder diffractometry, IR and X-ray photoelectron spectroscopy, electron microsonde analyses and ac conductivity measurements. The Agl content in the composite material is 11.5%. On the basis of the conductivity data obtained for the composite material as well as for K-ZSM5, Ag-ZSM5, microcrystalline AgI and a physical mixture of AgI and K-ZSM5, it has been inferred that, in the composite material, AgI forms a thin conductive shell on the surface of the K-ZSM5 particles.
