What is Emerging Applications of Zeolites in Catalysis, Separation and Host–guest Assembly about?

Zeolites are a class of inorganic crystalline materials with an orderly distribution of micropores of molecular dimensions (<2 nm) . Zeolites are typically built from TO 4 tetrahedra (where T is, for example, tetrahedrally coordinated Si, Al or P), which are connected by sharing oxygen vertices into rings, cages, channels and 3D tetrahedral frameworks . Although zeolites can be found in nature, the first synthetic zeolite, aluminosilicate mordenite (MOR type), was reported in 1948 (ref. 6 ). Many zeolites have since been synthesized to meet the ever-growing demands of industrial processes 7-10 ; examples include the aluminosilicate zeolites A (LTA type), X (FAU type), Y (FAU type) and ZSM-5 (MFI type); pure-silica silicalite-1 (MFI type); and the aluminophosphate AlPO-n series (Table ; box 1). Owing to their unique porous structures, zeolites can function as molecular sieves and selectively adsorb and separate guest species of specific sizes, shapes and polarities . Furthermore, the spatial confinement afforded by zeolite pores coupled with the catalytically active sites in their frameworks enables zeolites to function as unique shape-selective catalysts to direct the formation of
