Synthesis of Ttitanium Silicalite Mesoporous Material and Its Photocatalytic Performance on Toluene Decomposition

摘要

The world has td manage a tremendous set of environmental problems, and thus extensive research activities are carried on advanced chemical, biochemical, and physicochemical methods for elimination of hazardous chemical compounds from air and water. In this field, many works have been done on the photocatalytic treatment of environmental pollutants using semiconductors like TiO_2 and metal/TiO_2. However, the application has a limitation to use in industrial division because the performances observed were very low. In addition, the anatase structural limitation has been suggested, as a result, the photo-catalyst could be extended to introduce new structural titanium frameworks. In resent, Ti-incorporated or impregnated mesoporous materials were particularly introduced into photo-catalysis division, and the probability was shown in decomposition of aromatic compounds. In this study, mesoporous materials with a number of titanium are synthesized and the performances of adsorption and photodecomposition for toluene.
