The synthesized samples were characterized by XRD, UV-Vis and SEM. The results show that TS-1 crystals with uniform shape and size are self-stacked on top of another along the crystallographic [010] direction to form the fibrous morphology under suitable hydrothermal synthesis conditions. Compared with silicalite, the Ti incorporated into the MFI framework induces stronger condensation of external hydroxyl groups of TS -1 crystals, resulting in formation of the self-stacked morphology.
