Photocatalytic properties of TiO_2 supported on SB A-15 mesoporous materials with large pores and short channels

摘要

In this study, the new class of SBA-15 mesoporous materials with large pore diameter and short pore channels has been utilized as template for TiO_2 based photocatalysts. The samples were characterized by TEM, SAXS, and BET and tested for photocatalytic activity in liquid phase oxidation of phenol. This is the first ever application of this type of SBA-15 supported catalyst in photocatalytic area. This work also included the novel use of sub-1 nm Au nanoparticles for catalysts modification which doubles the phenol oxidation rate.
