分子筛间转化是一种合成分子筛骨架的技术，近年来已合成出大量高性能的催化分子筛。然而，沸石间转化成功背后的机制仍然未知。传统上，已经提出了在母体和子沸石之间具有结构相似性的小低聚物，尽管这些从未在实验中观察到。此外，最近的合成实例与母体和子沸石之间的结构相似性增强沸石间转化的理论相矛盾。从这个角度来看，提出杂原子，如铝，是决定母体沸石成功转化的过程中的关键参与者。通过修订大量文献，讨论了铝在母相溶解过程中以及结晶的所有连续阶段的作用。通过更好地理解铝在沸石间转化过程中的作用，有可能阐明一些一般特征，并提出一些用于制备有利的催化沸石的合成指南。后者的分析还扩展到存在锡等杂原子的沸石型材料的相互转化。铝在驱动和控制沸石间转化，一个有用的催化剂合成协议的关键作用，进行审查。
Interzeolite conversion, a synthesis technique for several zeolite frameworks, has recently yielded a large amount of high-performing catalytic zeolites. Yet, the mechanisms behind the success of interzeolite conversion remain unknown. Conventionally, small oligomers with structural similarity between the parent and daughter zeolites have been proposed, despite the fact these have never been observed experimentally. Moreover, recent synthesis examples contradict the theory that structural similarity between the parent and daughter zeolites enhances interzeolite conversion. In this perspective it is proposed that heteroatoms, such as aluminium, are key players in the processes that determine the successful conversion of the parent zeolite. The role of Al during parent dissolution, and all consecutive stages of crystallization, are discussed by revising a vast body of literature. By better understanding the role of Al during interzeolite conversions, it is possible to elucidate some generic features and to propose some synthetic guidelines for making advantageous catalytic zeolites. The latter analysis was also expanded to the interconversion of zeotype materials where heteroatoms such as tin are present. The crucial roles of aluminium in driving and controlling interzeolite conversion, a useful catalyst synthesis protocol, are put under scrutiny.
