    Synthesis of Ti-HMS Using Inorganic Ti Sources

    • 摘要: 用无机配合剂稳定钛酰离子,以正硅酸乙酯为硅源,十二胺为模板剂,用多种无机钛源合成了中孔Ti-HMS型分子筛,采用XRD,低温N2吸附,FT-IR和UV-Vis等方法对合成的含钛分子筛进行了结构表征,以苯乙烯的H2O2氧化作为模型反应,考察了合成的Ti-HMS分子筛的催化性能,结果表明,钛原子已进入分子筛骨架,用TiCl4为钛源合成的Ti-HMS分子筛在960cm^-1处存在较强的红外吸收,并对苯乙烯的H2O2氧化表现出较高的催化活性。

       

      Abstract: In this paper, a novel method for preparing mesoporous Ti HMS has been developed. By means of stabilizing Ti 4+ with H 2O 2, a s eries of Ti HMS have been synthesized using different inorganic titanic salts a s Ti sources. Being characterized by XRD, N 2 adsorption, FT IR and UV Vis, t he samples showed ordered mesoporous structure and Ti atoms have been incorporat ed into the framework. In catalyzing oxidation of styrene with hydrogen peroxide (H 2O 2), the Ti HMS samples prepared with inorganic Ti sources exhibits comp arable catalytic activity with that of Ti HMS prepared with organic Ti species( TBOT). The nature of inorganic titanic salts has considerable influence upon the incorporation of Ti into silica framework.
