Abstract
Intercalated materials based on natural montmorillonite and Fe- and mixed Fe/Al-polyhydroxo complex were obtained and their texture properties were studied. The catalytic properties of these materials were examined in the reaction of oxidation of an organic dye, Direct Pure Blue, with hydrogen peroxide in aqueous solutions. The optimal conditions of oxidation of azo dyes in the presence of intercalated clays were determined. In these conditions, a 100% oxidation of dye solutions can be achieved, with the stability of catalysts preserved.
