Advancing zeolite design via ionic liquid templating approach

Ionic liquids (ILs) have emerged as versatile tools in zeolite synthesis and structural modification, providing precise control over crystallization, morphology, porosity, and framework design. Their physicochemical properties, such as low vapor pressure, high thermal stability, and tunable polarity, enable their role as solvents, structure-directing agents (SDAs), porogens, and post-synthetic modifiers in zeolite formation. This article highlights the use of ILs in functionalized zeolite synthesis and modification, assessing their impact on zeolite topology, morphology, and the development of functionalized zeolites, including nanosized, hierarchical, and application-driven frameworks. By discussing recent advancements, we provide insights into the rational design and discovery of novel zeolite materials, fostering future innovations in catalysis, adsorption, and separation technologies.
