摘　　要：TS-1是一类独特的用于液相选择性氧化反应的分子筛催化剂,在高结晶沸石框架中具有四面体配位Ti^(4+)离子。TS-1/H_(2)O_(2)绿色反应体系已经取得了相当大的突破。TS-1分子筛的催化性能与其拓扑结构、晶体形态、四面体Ti的含量和反应微环境有关。当前石油化工和精细化工等行业对大分子氧化催化剂的需求日益增长,开发催化性能显著提高的新型TS-1的研究成为热点。综述TS-1分子筛近年的研究进展及催化应用。TS-1 is a unique heterogeneous catalyst for selective oxidation in liquid phase with tetrahedral coordination Ti^(4+)ions in a high crystalline zeolite framework.The TS-1/H_(2)O_(2) 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 performance.The research progress and catalytic application of TS-1 in recent years are reviewed in this paper.
