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.
