英文摘要: A three-dimensional sponge-like mesoporous, Ti-TUD-1 catalyst was synthesized by a direct hydrothermal treatment method. Its synthesis was modified to introduce more tetrahedral-coordinated Ti species into the framework of TUD-1 matrix, by controlling the hydrolysis of titanium and silicon sources. The TUD-1 catalyst was characterized by XRD, FT-IR, ICP-AES, UV-Raman, UV–vis DRS, BJH/BET and 29Si MAS NMR analyses, indicating that addition orders of substrate played a crucial role during the Ti-TUD-1 catalyst preparation, indicating the amount of tetrahedral-coordinated Ti species was closely related to the addition order of substrate. The presence of Ti species affected the internal structure and connectivity of TUD-1 matrix. The Ti-TUD-1 catalyst exhibited high catalytic...
