“…Recent advancement on MOF composites research has demonstrated that a rational combination of two components within a composite promotes positive synergistic effects and simultaneously moderates the drawbacks of the single materials. [78] Several examples of MOF composites with graphene, [79] graphene oxide, [80] MCM-41, [81] ionic liquids, [82] clays [83] and polymers [84] have been developed and successfully applied to CO 2 adsorption, aiming to synthesize a material for CO 2 capture.…”

“…In this case, a 30 % increase in the CO 2 adsorption capacity compared to pristine MCM-41 was demonstrated. [81] In a comparative study the effects of combining ionic liquids (ILs) and MOFs were investigated, incorporating [BMIM] [BF 4 ] and [BMIM][PF 6 ] into MIL-53(Al), HKUST-1, and ZIF-8. [82a] The ILs had a negative effect on the CO 2 adsorption capacity of HKUST-1 since they bind at the unsaturated copper sites.…”

The dramatic increase of atmospheric CO2 concentration is responsible for a fast and potentially unpredictable global climate change. Therefore, the implementation of negative carbon technologies such as direct air capture (DAC) is needed. Metal–organic frameworks (MOFs) have the potential to perform CO2 DAC and achieve unprecedented performances. Herein strategies to improve the CO2 capture efficiency of MOFs and their potential implementation in real applications are discussed. Three main categories of targeted modifications to the frameworks are usually performed to enhance the CO2 uptake capacity and adsorption selectivity: 1) modifications to the metal unit; 2) modifications to the linker unit; 3) confinement of solvents within MOFs. The synthesis of MOF composites using other porous materials as support is also a useful method to improve the CO2 capture performances. Another approach involves the synthesis of amine‐functionalized MOFs that can chemically bind carbon dioxide.

“…In MOF chemistry, one-pot synthesis is oen used to prepare MOF-hybrids or MOFs with additional functionality as the porous structure can be further functionalised by the secondary reaction. Examples of one-pot microwave-assisted syntheses of MOF hybrids include; MOF-silica 131,132 and MOF-alumina 131 composites; a photochromic indium trimesate (trivial MOF name, JUC-120) hybrid lm produced by entrapping guest molecules within the framework; 133 a catalyst for alcoholysis of styrene oxide produced by doping MIL-101(Cr) with phosphotungstic acid; 134 and a heterogeneous catalyst for microwave heated organic coupling reactions comprising of IRMOF-3 doped with silver nanoparticles synthesised from the MOF precursor solution and silver nitrate. 111 In the latter example the sizes of silver nanoparticles were controlled by altering the reaction time.…”

Metal-organic frameworks (MOFs) are a broad class of porous crystalline materials that show great potential for a wide-range of applications in areas such as energy and environmental sustainability. MOFs can show significant advantages in gas selectivity and separation over traditional adsorbents such as zeolites and activated carbons since they are tuneable both in terms of porosity and chemical functionality. The ability to control the pore environment of the MOF is one of their remarkable advantages and affords control over the structure and properties required for specific applications.Despite these advantages, the industrial adoption of MOFs is slow owing to the paucity of scalable, environmentally sustainable manufacturing methods and higher costs compared to zeolites. Microwave (MW) technology is an extremely promising method of MOF production owing to significantly reduced reaction times and subsequently lower process energy consumption, control over MOF properties, and the ability to produce MOFs and MOF-hybrids otherwise difficult to isolate or unobtainable through other synthetic routes. However, the ability to produce the multiple kilogram or even tonne quantities of MOFs required by industry using MW technology is yet to be achieved owing to little or no understanding of the interaction(s) of reactants and MOFs with the electric field, and crucially, how this informs the design of the scale up processes. This review aims to bridge this gap in knowledge by (1) highlighting recent advances in understanding of MW-MOF interactions and areas for future focus; (2) providing an up-to-date and comprehensive summary of literature on MW synthesis of MOFs, focusing on examples where MW heating has facilitated novel and unique results in the laboratory; and (3) emphasising the advantages, challenges and current steps and methodologies required towards industrial-scale MW production of MOFs.
