Recent progresses and application of titanosilicate-1
TS-1 is a unique heterogeneous catalyst for selective oxidation in liquid phase with tetrahedral coordination Ti4+ ions in a high crystalline zeolite framework. The TS-1/H2O2 green reaction system has made a considerable breakthrough. The catalytic performance of TS-1 zeolite is related to its topological structure,crystal morphology,framework Ti content and reaction microenvironment. At present,the growing demand for macromolecular oxidation catalysts in petrochemical industry and fine chemical industry has set off a wave of research on the development of novel TS-1 with significantly improved catalytic perform-ance. The research progress and catalytic application of TS-1 in recent years are reviewed in this paper.
