The most advanced synthesis and a wide range of applications of MOF-74 and its derivatives

This review summarizes the latest synthesis methods, characterization and corresponding applications of MOF-74 and its derivatives in recent years. Metal-organic frameworks (MOFs) are nanomaterials with many attractive advantages, such as good stability, large specific surface area and large apertures, which make them receive considerable attention. Among them, MOF-74 is a particularly outstanding one attribute to its excellent CO2 adsorption capacity. MOF-74 can be synthesized directly from a metal oxide and without bulk solvent, which not only saves a lot of time and money, but also is more ecological. The mesopores in MOF-74 can be adjusted to as large as 15 nm stably at room temperature. And characterization results show MOF-74 possesses good hydrolysis stability, highly stable structure, gas adsorption capacity, catalytic activity and so on. In addition, multifarious synthetic materials with additional functionality can be obtained by properly combining MOF-74 with other components. Therefore, MOF-74 has great potential and has aroused great enthusiasm for research in many aspects, such as gas adsorption, separation, and catalysis and so on.
