| Résumé: | The different properties developed by the clays such as; their capacities of
exchanges cationic and their properties of surface were showed by several works. These properties
confer to the clay important adsorption properties. They can acquire other properties by various
modifications which can be through chemical, physical and/or thermal view. These new properties may
open the ways of unsuspected applications: adsorption and catalysis.
In this work, we have studied the pillaring of the upper Cretaceous natural Tunisian clays
taken from Jebel Nahli with polyhydroxymetallic precursor [Al
13O4 (OH)24(H2O)12
7+
]. Several
techniques are used, in this study: XRD, infra red spectroscopy, thermogravimetric analysis, textural
measures and scanning electron microscopy. The results show that the pillaring of smectitic clays with
Aluminum oxides polycations has allowed obtaining microporous materials, rigid, with a large
interlayer spacing and a high thermal stability. |
