Zeolites have been conventionally synthesized using organic structure directing agents (OSDA) in solvent. In this work, we synthesized various zeolites from unseeded aluminosilicate via mechanochemical and vapor treatments in the absence of OSDA and solvent. Various types of zeolites were successfully synthesized from starting materials with different Si/Al ratios. With an increase of Si/Al from 1 to 20, different phases appeared in the order of CAN, ANA, MOR, MFI and α-quartz. This work provides a new insight of zeolite synthesis.

通过机械化学和蒸气处理将无种子的硅铝酸盐无溶剂/ OSDA转化为各种沸石

常规上已经使用有机结构定向剂（​​OSDA）在溶剂中合成了沸石。在这项工作中，我们在不存在OSDA和溶剂的情况下，通过机械化学和蒸气处理，从非种子铝硅酸盐合成了各种沸石。从具有不同Si / Al比的原料成功地合成了各种类型的沸石。随着Si / Al从1增加到20，以CAN，ANA，MOR，MFI和α-石英的顺序出现了不同的相。这项工作为沸石合成提供了新的见解。
