Abstract—Titanium-doped 13X molecular sieves (Ti/13X) were type TiO2 has been the best photocatalysts reported so far. But
essfully prepared by the impregnation method. The its photocatalytic efficiency was greatly constrained because of
incorporation of Ti into the representative Ti/13X sample with a the characteristically poor adsorption and low surface area
large number of wormhole-like channels was readily established properties. Consequently, various forms of TiO2 materials
by both X-ray diffraction (XRD) patterns and scanning electron (suspended, unsupported and immobilized) were developed for
microscopic (SEM) micrographs. The photocatalytic efficiency of photocatalytic applications [9].
various Ti/13X samples was then evaluated by their ability of
removing a reactive dye X-3B from the artificial dye wastewater. Supported TiO2 is generally found less photoactive as the
Several major factors which might govern the photocatalytic re
