摘要

通过在 YFI 框架中用 Ti 对 Al 进行后合成异构取代，制备了具有 YFI 拓扑结构的新型大孔钛硅酸盐 [Ti]-YNU-5。它在大块烯烃的液相环氧化反应和苯酚与过氧化氢的氧化反应中表现出更强的催化性能。疏水性是一个重要因素。

[Ti]-YNU-5: a large-pore titanosilicate as an efficient catalyst for selective oxidations

A novel large-pore titanosilicate with YFI topology, [Ti]-YNU-5, was prepared via post-synthetic isomorphous substitution of Ti for Al in the YFI framework. It exhibited the enhanced catalytic performances in the liquid-phase epoxidation of bulky alkenes and the oxidation of phenol with hydrogen peroxide. Hydrophobicity was found to be an important factor.
