立方介孔分子筛Zr-SBA-1的合成及表征

Synthesis and Characterization of Cubic Mesoporous Sieves Zr-SBA-1

在强酸性条件下以十六烷基三甲基溴化铵为模板剂，TEOS为硅源，沿S^＋X^-I^＋途径合成了Zr含量为0．85-2．42％的介孔分子筛Zr-SBA-1．采用XRD、SEM、BET、DR UV—Vis等技术对所合成的Zr-SBA-1的表征结果表明，所合成的Zr-SBA-1分子筛具有典型的立方相介孔结构SBA-1分子筛的特征，锆物种被成功引入分子筛骨架中．

A series of Zr-SBA-1 with different content of Zirconium（0.85% - 2.42% ） were synthesized using CTEABr as template by the ＂S^ ＋ X^- I^ ＋ ＂ route under strong acid condition. The structure and morphology of assynthesized Zr-SBA-1 were characterized by XRD, SEM, BET, DR UV-vis techniques. The results showed that as-synthesized Zr-SBA-1 have typical feature belong to SBA-1 mesoporous sieves. The incorporated Zirconium species existed in a highly dispersed state and had tetrahedral coordination.
