- Abstract
We synthesized Ti-containing SBA-15 by one-pot hydrothermalmethod and extensively investigated its physicochemical properties and examined its photocatalytic activity to degrade phenol. It's shown that appropriate amount of titanium could be effectively incorporated into the framework of SBA-15 without provoking structure change and the tetrahedrally coordinated titanium species werewell-ordered in Ti-incorporated SBA-15.UnderUV-irradiation, the Ti-containing SBA-15 exhibits good photocatalytic activity for phenol degradation in the simulated waste water. The higher photocatalytic activity of Ti-containing SBA-15 to degrade phenol was ascribed to the more titanium content and anatase titanium dioxide. In addition, the new photocatalyst displays a good regeneration and cyclic performance after six runs.
