Beschreibungen/Notizen

• Na-montmorillonite purified either by dialysis or by multiple centrifugation was used for the preparation of two types of clay mineral/TiO2 composites: one obtained by conventional pillaring, the other by mixing of organo-montmorillonite with inverse micelles containing Ti oxo-hydroxy species. The manner of preparation of the parent clay mineral affected strongly the textural properties of pillared montmorillonite materials but had much less effect on the texture of composites prepared with inverse microemulsion. The observed phenomena are discussed in terms of the montmorillonite component structural organization upon formation of composites. Suitability of both purification methods for preparation of Na-montmorillonite designed for synthesis of composite materials is assessed.
