Paper Abstract

Novel nano TS-1, Ti-MCM-41 and Ti-SBA-15 analogues were successfully synthesized by hydrothermal treatment using TS-1 nano-seeds as precursors. The samples were characterized by IR, XRD, FESEM, TEM and BET. The characterization results revealed that the synthesized TS-1 had microstructure with crystal size of 50 - 60 nm, Ti-MCM- 41 and Ti-SBA-15 analogues had mesostructure with high ordering. The samples were tested in photocatalytic oxidation of Red Phenol and in photocatalytic reduction of Cr(VI) to Cr(III). The samples exhibited high activities in both reactions. Photocatalytic performances of all samples were compared and discussed.
