Holey moly! The introduction of large pores is known to be an efficient method to overcome performance constraints of zeolites caused by diffusional limitations. The substitution of framework atoms with Ti is essential for epoxidation catalysis. Combining both post-synthesis steps provides high-performance epoxidation catalysts particularly for large substrates at significantly reduced cost.

通过同时脱硅和钛化获得的分层Ti-β作为高效的环辛烯环氧化催化剂

多孔的钼！已知引入大孔是克服由扩散限制引起的沸石性能限制的有效方法。用Ti取代骨架原子对于环氧化催化至关重要。结合两个后合成步骤可提供高性能的环氧化催化剂，尤其适用于大型基材，且成本大大降低。
