ABSTRACT

Zeolites have been successfully synthesized for several decades, the roles of templates for zeolite synthesis were still not fully understood yet. Currently, many types of templates have been employed such as inorganic alkali metal ions, organic quaternaryammonium cations, organic amines, organic quaternaryphosphonium cations, metal complexes, and zeolite seeds, where the roles are mainly summarized into three aspects: structure-directing, space-filling, and charge-balancing. In order to synthesize zeolites efficiently, it is proposed principles to guide zeolites synthesis such as stabilization of energy between templates and zeolites framework, charge density mismatching, structure matching between zeolite frameworks and templates. The purpose of this review is to briefly summarize the progresses in recent years, clearly showing the roles of the templates for zeolite synthesis.
