Preparation of Photoactive TiO2/LTA Zeolite Composites by Solution Technology in Hydrothermal Conditions
For the first time, using solution technology in a reactor under pressure, composites of titanium oxide and LTA zeolite containing 50, 70, and 80% TiO 2 were obtained. The materials were characterized by XRD, IR spectroscopy, SEM, energy-dispersive microanalysis, and low-temperature nitrogen adsorpt...

were obtained. The materials were characterized by XRD, IR spectroscopy, SEM, energy-dispersive microanalysis, and low-temperature nitrogen adsorption–desorption. The adsorption and photocatalytic properties of the composites were studied using the model dye Rhodamine B as an example. The surface morphology and the textural, adsorption, and photocatalytic properties of the resulting composites, as well as the phase composition of TiO
2
, largely depend on the degree of coverage of the surface of the zeolite. For 80% TiO
2
/LTA composites, a degree of coverage close to 100% was observed, and it is for this composition, with a size of TiO
2
crystallites of about 11 nm and an anatase/rutile phase ratio of about 0.54, that the highest photocatalytic activity was found. |
