Abstract:

Zeolites have been widely used in ion-exchange, sorption and separation as well as catalysis fields due to their large surface area, high adsorption capacity, uniform and intricate channels, high thermal and hydrothermal stabilities, and well-defined micropores with excellent shape-selectivity in catalysis. In recent years, a series of breakthrough achievements has been made in the fundamental research of zeolites in China. This manuscript will briefly summarize these progresses including the accelerated crystallization of zeolites via hydroxyl free radicals, construction of stable aluminosilicate zeolite with extra-large pores, in-situ imaging of topological flexibility of a rigid zeolite framework as well as atomic imaging of zeolite-confined single molecules by electron microscopy, excellent performance in adsorption-separation and catalytic transformation of small hydrocarbon molecules, and flexible zeolite electrolyte solid-state Li-air battery. Prospective and challenges in the fundamental research of zeolites will also be conveyed.
