Design and synthesis of multifunctional metal–organic zeolites

Abstract

Metal-organic zeolites (MOZs) are an important branch of metal-organic frameworks (MOFs) and combine the advantages of zeolites and MOFs, such as high surface area and porosity as well as the exceptional stability of zeolites, which would have a significant impact on catalysis chemistry, inorganic chemistry, coordination chemistry, materials science and other areas. In this review, we focus on the recent advances in MOZs with a brief outline of the most prominent examples. In particular, we highlight the basic principles of the design and synthesis approaches toward the construction of MOZs. Obeying the principle of charge matching, tuning tetrahedral metal centers, using enlarged tetrahedral building units as clusters, introducing functional groups into ligands, and combining traditional inorganic TO sites in MOZs enable the final materials with diverse topological structures to exhibit superior performance for various applications, such as gas sorption/separation, catalysis, enantio-selectivity, luminescence, etc.

Freestanding 1D Hierarchical Porous Fe‐N‐Doped Carbon Nanofibers as Efficient Oxygen Reduction Catalysts for Zn–Air Batteries

“…[14][15][16][17][18][19][20][21] For example, a couple of iron-nitrogen-doped porous carbon materials have been prepared through the carbonization of Fe-MOF precursors or Fe-encapsulated MOFs, which demonstrated an excellent ORR activity and high selectivity. [22][23][24] However, the MOF-derived carbon catalysts retaining the initial morphology and features of the parent MOFs usually evolve into isolated nanoparticles with the presence of micropores, which largely lowers the conductivity and hence results in the weakening of their electrochemical property. It is worth noting that 1D carbon materials, such as carbon nanotubes (CNTs) and carbon fibers (CFs), in essence have prior electron channeling and high strength-to-weight ratios.…”

A new route to triphenylpyridines utilizing ketoximes as building blocks via cascade reactions under iron‐organic framework catalysis

“…[16][17][18][19] Owing to their diverse porous structures with various connectivity and symmetry, MOFs have been extensively explored for applications in numerous fields, ranging from adsorption to biomedical engineering. [20][21][22] Highlighted by permanent porosity, adjustable internal surface functionality, and concentrated active sites, MOFs have emerged as promising candidates for catalysis. [23][24][25] Catalytically active sites could be generated on both organic and inorganic components in the framework, therefore offering significant advantages over conventional catalytic materials.…”

Recent Advances in Zeolite‐like Cluster Organic Frameworks

“…[5] Owing to the interesting topology and important utilization of zeolites, an increasing number of chemists are searching for suitable reaction systemst hat can be used to design and synthesize porousm aterials by mimickingt he features of inorganic zeolites. [6][7][8][9][10][11][12] Metal-organic frameworks (MOFs) are ab urgeoning class of crystalline microporous materials composed of metal ions/clusters as nodes and organic ligandsa sl inkers, and they have become one of the fastestd eveloping fields in materials chemistry because of their designable structures,t unable functions, and high surfacea reas. [13,14] These advantages allow MOFs to play ap ivotalr ole in functional applications, such as gas storagea nd separation, [15][16][17][18] sensing, [19,20] drug delivery, [21,22] and luminescence.…”
