“…Comparing with the diffraction patterns of neat 13X molecular sieves, M8 sample exhibits new diffraction peaks at the values of 25.18 o , 31.58 o and 45.32 o that correspond to the presence of titanium dioxide anatase[18,10,14], indicating the successful incorporation of Ti into the framework of 13X molecular sieves.…”

“…Furthermore, adulteration of Ti atom into the materials with well-defined pore and channel structures, such as zeolites [11], silica [12], alumina [13], and mesoporous molecular sieves [14], has caught increasing attention as promising photocatalysts due to their enhanced adsorption properties, in which the doped Ti atoms serve as catalytic sites. However, as far as is known, little has been reported on the degradation of azo dyes by microporous molecular sieves-based photocatalysts.…”

Titanium-doped 13X molecular sieves (Ti/13X) were successfully prepared by the impregnation method. The incorporation of Ti into the representative Ti/13X sample with a large number of wormhole-like channels was readily established by both X-ray diffraction (XRD) patterns and scanning electron microscopic (SEM) micrographs. The photocatalytic efficiency of various Ti/13X samples was then evaluated by their ability of removing a reactive dye X-3B from the artificial dye wastewater. Several major factors which might govern the photocatalytic reaction, such as the dosage of Ti/13X, reaction time, pH and concentration of X-3B were thus considered and checked. Finally, we found that the degradation reaction of Ti/13X with X-3B fitted well into the first-order kinetics.
