摘要： 通过3种不同的水热晶化法合成了Ti-ZSM-11型分子筛,并利用XRD、SEM、IR、TG-DTA、XPS、DRS等手段对其进行了表征。结果表明,Ti进入了分子筛骨架,且Ti含量增加,晶胞参数增大,IR谱中～970cm-1的谱带逐渐增强。热分析表明,Ti-ZSM-11有较好的热稳定性,苯乙烯选择氧化结果表明,沸石中Ti含量增加,反应活性提高,活性中心Ti是孤立的连接,而不是彼此邻近相连。

Abstract: Ti-ZSM-11 zeolite was synthesized by three different hydrothermal crystalline methods.The structure and properties were investigated by XRD,SEM,IR,TG-DTA, XPS, DRS. The results show that Ti4+occupies Tsite of the framework of the zeolite, The unit cell parameters and the intensity of the ～970 cm-1band in IR spectra increase with in creasing Ti content,as well as the activity of the selective oxidation of styrene.At the active centres,the Ti(Ⅳ)are isolated from each other and form long sequences, not having other Ti(Ⅳ)as neighbours.The oxidative abilities of TS-2 are similar to three different porphyrins in their catalytic properties.
