有机硅烷偶联剂(KH550)导向制备层状钛硅酸盐

摘要在碱性环境下，采用四氯化钛作为钛源、白炭黑作为硅源，有机硅烷偶联剂（KH550）做结构导向剂，通过溶胶-凝胶法合成有机硅烷偶联剂插层层状钛硅酸盐（KH-LTS）。样品的结构和稳定性通过X-射线衍射、红外光谱、紫外-可见光谱、差热热重、扫描电镜和透射电镜进行表征。结果表明，复合材料KH-LTS具有有序的层状介观结构，其层间距约为3.2 nm，实验结果为交换插层及石油的裂解催化提供了依据。

Abstract： In alkaline environment, organosilane coupling agent intercalated titanium silicate (KH-LTS) was synthesized via sol-gel method by using titanium tetrachloride as titanium source, silica as silica source and organic silane coupling agent (KH550) as structure-directing agent. The structure and stability of the composites were characterized by XRD, infrared spectroscopy, TG and SEM. The results show that the KH-LTS has ordered layered mesoscopic structure, and the interlayer spacing is around 3.2 nm. The layered structure is stable in a alkaline environment, unstable and easy to be destroyed in acidic environment, which provides a theoretical basis for exchange intercalation and pyrolysis of petroleum.
