Interests: the heterogeneous catalysis using various nanostructured materials
Zeolites are central in many industrial and chemical engineering processes involving solid catalysts, which have attracted a great deal of attention from chemists, chemical engineers, and materials scientists. This family of nanoporous crystals was first discovered in 1756 and, since then, about 40 zeolites structures have been found in nature, and about 160 structures, to date, have been synthesized artificially in the lab. The regularly-arranged micropores within stable crystalline architectures afford useful functions to zeolite catalysts, such as size/shape selective catalytic ability and high thermal/hydrothermal/mechanical stabilities. In this regard, a great deal of research regarding the synthesis of zeolites, with better functions, as well as their catalytic applications, has been performed so far, and broad knowledge has been accumulated over the decades. For example, in addition to the aluminosilicate-type classical zeolites, various transition metal-incorporated zeolites have been synthesized, which is reminiscent of the heterogenized version of transition metal complexes. The tiny micropores often limit their catalytic regime to only sufficiently-small molecular species that can go through the pore aperture, but such a limited applicability has also been considerably improved by the generation of larger pores in a mesopore range.
The aforementioned research works on the development of various synthetic zeolites, having better catalytic performances, has guided current industrial society to a brighter and greener world. The aim of the present Special Issue is to report the latest research advances in the synthesis and characterization of zeolites and their catalytic applications in experimental and theoretical manners. Broad contributions, including other crystalline nanoporous materials and their catalytic applications, would also be valuable subjects to widen the scope of this Special Issue.

Abstract: Zeolite crystals with unique pore structure, adjustable acidity, high surface area and high hydrothermal stability have been widely used in petrochemicals and fine chemical industries. Hierarchical zeolites have been extensively studied due to their promoting diffusion capability leading to great improvance in activity and coking-deactivation resistance . However, traditional synthesis strategy for hierarchical zeolties is characteristic of high energy consumption, high discharge and high pollution with numerous waste water and organic templates. In recent 10 years, a series of green synthesis routes of hierarchical zeolites have been developed by improving traditional synthesis methods or adopting new synthesis methods. In this review, latest advances on the green synthesis of hierarchical zeolite is summarized and discussed in detail. The problems and future direction of the green synthesis are also proposed.
