Illuminating solvent-free synthesis of zeolites

Abstract

With the merits of the accelerated crystallization process, high volume yields, and reduced waste production, solvent-free syntheses give new opportunities for the fabrication of zeolites. In this Frontier, a background overview is provided, consisting of a brief introduction of challenges in traditional zeolite syntheses and how solvent-free syntheses provide the right combination of properties for achieving a more sustainable route. Next, recent advancements in zeolites synthesized under solvent-free conditions are exemplified along with discussions about the strategies and principles involved. Finally, the remaining challenges and opportunities for this synthetic route are outlined.
