“…Furthermore, they show considerable applicability to the improvement of industrial viability of powdered MOFs [21]. However, the major factor associated with the industrial application of monolithic MOFs is minimizing the loss of porosity when shaping and providing sufficient mechanical stability, which are necessary for engineering processes [33,34]. Therefore, advantages and disadvantages must be considered and shaping technologies must be optimized based on the inherent properties and practical applications of the specified MOFs.…”

Although considerable achievements have been realized in recent years with respect to the syntheses of metalorganic frameworks (MOFs), majority of the developed MOFs are in the form of polydisperse microcrystalline powders, which cause dustiness, abrasion, and clogging and decrease pressure when used in industrial applications. Monolithic MOFs overcome these drawbacks and exhibit various promising characteristics. In this review, we present the recent advances associated with monolithic MOFs based on metal centers and a brief outline of the most prominent examples. Furthermore, the challenges and prospects associated with monolithic MOFs in terms of large-scale production and engineering applicability are analyzed based on our knowledge to conclude this review.

“…MOFs have been rapidly emerging as a very powerful platform for constructing multifunctional materials. [ 30,31 ] These frameworks with tunable pore sizes and functional surfaces have emerged as promising materials for confined ion transport studies. [ 32 ] In the past few decades, several studies have been conducted to synthesize high‐quality MOF membranes using various methods (such as solvothermal synthesis, hot pressing, secondary growth, and contra‐diffusion synthesis and electrochemical synthesis).…”

Biological ion channels with delicate ion transport functions exist widely in living organisms. Bioinspired solid‐state channels have emerged as promising platforms to mimic the working mechanism of natural channels. These channels help in understanding the mechanism of ion transport in biosystems and pave the way for applications in several interesting areas. Metal‐organic frameworks (MOFs), constructed by connecting metal ions and organic ligands, exhibit high porosity and unique pore structures. They also possess tunable pore sizes and are versatile in their compositions. And there are rich molecule/ion‐specific functional groups in the frameworks, which can intelligently modulate ion transport. Thus, MOFs are promising candidates that mimic biological ion channels. Herein, the recent progress in the design and construction of artificial solid‐state MOF‐based channels is focused on. The excellent ion transport properties of MOF‐based membranes are also summarized, including ionic selectivity, ionic rectification, and ionic gating. Following this, four emerging ion transport applications, namely, energy conversion, ion/molecule separation, biosensing, and water desalination, are highlighted. Finally, an outlook on future developments and challenges in this exciting research area is presented.

“…There has been a substantial increase in interest of MOFs owing to their attractive physicochemical characteristics such as high surface area, permanent porosity, abundant active sites, and flexible chemical structure [4][5][6][7][8][9]. To date, the main focus of MOF investigations is the optimization of their structures or properties, such as increasing the crystallinity and pore size, to develop their potential applications in gas storage [10][11][12][13], adsorption and separation [14][15][16][17], large molecule encapsulation [18][19][20], supercapacitors [21][22][23], energy conversion [24,25], chemical sensors [26][27][28], biomedicine [29,30], and catalysis [31][32][33]. However, the synthesis conditions of MOFs for eco-friendly and industrial scale-up were only sparsely investigated in both research and industrial laboratories [34,35].…”

Water-based routes for synthesis of metal-organic frameworks: A review

et al. 2020

Although metal-organic frameworks (MOFs) show numerous advantages over other crystalline materials, their industrial relevances have been impeded owing to their many drawbacks such as environmental impacts and economic costs of their synthesis. A green preparation pathway could greatly reduce the environmental costs, energy, and the need for toxic organic solvents, and consequently reduce the production cost. Thus, the most desirable synthesis route is the replacement of harsh organic solvents with aqueous solutions to abate environmental and economic impacts. This review summarizes recent research advancements of water-based routes for MOF synthesis and gives a brief outline of the most prominent examples. The challenges and prospects of the commercialization of promising MOFs in the future are also presented. This study aims to offer necessary information regarding the green, sustainable, and industrially acceptable fabrication of MOFs for their commercial applications in the future.
