A pure silica STW zeolite is synthesized with no impurities under a wide range of synthesis conditions with and without fluoride by using easily available 1-methyl-1,5-diazabicyclo[4.3.0]non-5-ene (MDBN) as a template. MDBN having an appropriate size and geometry fits well in the STW cage, leading to its high specificity in structure-directing formation of zeolite STW.

使用设计的有机结构导向剂合成的无氟硅质 STW 型沸石

使用容易获得的 1-甲基-1,5-二氮杂双环[4.3.0]非 5-烯 (MDBN) 作为模板,在含氟和不含氟的各种合成条件下合成不含杂质的纯二氧化硅 STW 沸石. 具有适当尺寸和几何形状的 MDBN 非常适合 STW 笼,导致其在沸石 STW 的结构导向形成中具有高度特异性。
