FORMATION OF TiO₂/MICA COMPOSITE FOR PHOTOCATALYSIS

Abstract

The design results of the composites TiO₂/mica photocatalytic active sheet are presented. For producing of initial powders elements of sol-gel and freeze-drying were used. The tape casting of TiO₂/mica water slurry with using of doctor blade apparatus were used for forming of sheets. The phase composition, the specific surface area, the porous distribution and morphology of the produced powders and materials were investigated. It is established that the resulting TiO2 pillared mica sheet possesses good photocatalytic properties determined by gaseous acetaldehyde removal measurement.
