Direct Synthesis and Characterization of Ti-SBA-15 with Different Ti Precursors

Abstract:

Titanium substituted SBA-15 mesoporous materials have been prepared by direct synthesis under hydrothermal conditions. Ti-SBA-15 was prepared by TiCl₄ and Tetrabutyl titanate (TPOT) as titanium precursor. The synthesized materials were characterized by X-ray diffraction (XRD), UV-Vis spectrometer (UV-Vis), N₂ adsorption/desorption, SEM etc. The results exhibited that the synthesis of mesoporous materials are ordered, and Titanium is tetrahedral and highly dispersed through the inside of SBA-15. Spherical particles of mesoporous have been synthesized by TPOT. The mesoporous materials synthesized by TiCl₄ had non-uniform particle morphology. The titanium precursor TPOT incorporation in SBA-15 makes surface area increase due to make the pore walls slimmer. The titanium precursor TiCl₄ had great influence of the particle morphology and pore characters and no influence on crystal structure.
