Abstract

This review explores the features and corresponding application of ZIF-67 and its derivatives. Thermally and chemically stable zeolitic imidazolate framework (ZIF) materials have received extensive research and application interest. In particular, ZIF-67 can be synthesized by a facile and environmentally friendly organic synthesis method. The nanostructures and mean particle sizes of ZIF-67 can be adjusted by controlling experimental conditions carefully. The resulting ZIF-67 possesses the characteristics of a tunable pore aperture, highly stable structure, catalytic activity and so on. Furthermore, by combining the advantages of ZIF-67 and various components or structures, the resulting compounds have a potentially better performance than pure ZIF-67. Therefore, ZIF-67 and its derivatives have aroused great interest of scientists and have the potential to be applied to gas adsorption, molecular separation, electrochemistry, catalysis and so on.

Exceptional chemical and thermal stability of zeolitic imidazolate frameworks.

K S Park, Z. Ni, A P Côté … (2006)

Twelve zeolitic imidazolate frameworks (ZIFs; termed ZIF-1 to -12) have been synthesized as crystals by copolymerization of either Zn(II) (ZIF-1 to -4, -6 to -8, and -10 to -11) or Co(II) (ZIF-9 and -12) with imidazolate-type links. The ZIF crystal structures are based on the nets of seven distinct aluminosilicate zeolites: tetrahedral Si(Al) and the bridging O are replaced with transition metal ion and imidazolate link, respectively. In addition, one example of mixed-coordination imidazolate of Zn(II) and In(III) (ZIF-5) based on the garnet net is reported. Study of the gas adsorption and thermal and chemical stability of two prototypical members, ZIF-8 and -11, demonstrated their permanent porosity (Langmuir surface area = 1,810 m(2)/g), high thermal stability (up to 550 degrees C), and remarkable chemical resistance to boiling alkaline water and organic solvents.

Metal-organic framework materials as catalysts.

JeongYong Lee, Omar K. Farha, John Roberts … (2009)

A critical review of the emerging field of MOF-based catalysis is presented. Discussed are examples of: (a) opportunistic catalysis with metal nodes, (b) designed catalysis with framework nodes, (c) catalysis by homogeneous catalysts incorporated as framework struts, (d) catalysis by MOF-encapsulated molecular species, (e) catalysis by metal-free organic struts or cavity modifiers, and (f) catalysis by MOF-encapsulated clusters (66 references).

Reticular synthesis and the design of new materials.

Omar Yaghi, Michael O'Keeffe, Nathan W Ockwig … (2003)

The long-standing challenge of designing and constructing new crystalline solid-state materials from molecular building blocks is just beginning to be addressed with success. A conceptual approach that requires the use of secondary building units to direct the assembly of ordered frameworks epitomizes this process: we call this approach reticular synthesis. This chemistry has yielded materials designed to have predetermined structures, compositions and properties. In particular, highly porous frameworks held together by strong metal-oxygen-carbon bonds and with exceptionally large surface area and capacity for gas storage have been prepared and their pore metrics systematically varied and functionalized.
