The photochemistry of dibenzyl ketone and its derivatives has been employed to investigate the ability of zeolite molecular sieves to modify and to control the reaction channels available to organic molecules adsorbed on the internal and external zeolite surfaces. It is found that the observed photochemistry is very sensitive to the size/shape characteristics of the substrate ketones and of the...

Immobilization of catalysts on the surface of some inert supports makes therecovering step easier. Because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. In this study, zeolite X was synthesized by natural kaolin and TiO2 was incorporated into zeolite phase by impregnation method. Degradation of Safranin Orange, methylene blue and 2,4–di...

The preparation and properties of zeolite-containing oxide coatings obtained by plasma electrolytic oxidation are investigated discussed. Pure Ce-exchanged natural (clinoptilolite) synthetic (13X) zeolites immobilized on aluminum support from silicate-based electrolyte. Obtained characterized with respect to their morphology, phase chemical composition, photocatalytic activity anti-corrosion pr...
