By combining a rational design of structure directing agents and high throughput and data mining techniques, it has been possible to obtain Ge-free ITQ-24 as pure silica as well as borosilicate polymorphs up to a Si/TIII ratio of 10. Al can be exchanged by B giving strong acid materials. Also, the availability of the pure silica material allows one to determine more precisely the crystal symmetry. This work opens the possibility to synthesize the Ge-free polymorphs of a large number of new germanosilicate structures reported in the last five years. This certainly will increase their possibilities for industrial application.
通过将结构导向剂的合理设计与高通量和数据挖掘技术相结合，已能够获得纯二氧化硅形式的无锗ITQ-24以及硅/三价阳离子比高达10的硼硅酸盐多晶型物。铝可以被硼取代，从而得到强酸材料。此外，纯二氧化硅材料的可得性使人们能够更精确地确定晶体对称性。这项工作为合成过去五年报道的大量新型锗硅酸盐结构的无锗多晶型物开辟了可能性。这必将增加它们在工业应用中的可能性。
