Pillared Sn‐MWW (Sn‐MWW(SP)‐SSE) was prepared through a solid‐state‐exchange (SSE) route. The pillared structure was inherited from pillared B‐MWW, and Sn was inserted in the framework by boron leaching and solid‐state‐exchange with tin tetrachloride pentahydrate. The Sn‐MWW(SP)‐SSE with framework Sn sites exhibits Lewis acidity and good catalytic performance for the Baeyer–Villiger oxidation, and
通过固态交换(SSE)路线准备了柱状Sn-MWW(Sn-MWW(SP)-SSE)。柱状结构是从柱状B-MWW继承而来的,并且通过硼浸出和与五水合四氯化锡的固态交换将Sn插入到框架中。具有骨架锡位点的Sn-MWW(SP)-SSE表现出路易斯酸度,对Baeyer-Villiger氧化以及单糖和二糖异构化具有良好的催化性能。
