Hierarchical Metal–Organic Frameworks with Macroporosity: Synthesis, Achievements, and Challenges

Nano-Micro Letters

Introduction of multiple pore size regimes into metal–organic frameworks (MOFs) to form hierarchical porous structures can lead to improved performance of the material in various applications. In many cases, where interactions with bulky molecules are involved, enlarging the pore size of typically microporous MOF adsorbents or MOF catalysts is crucial for enhancing both mass transfer and molecular accessibility. In this review, we examine the range of synthetic strategies which have been reported thus far to prepare hierarchical MOFs or MOF composites with added macroporosity. These fabrication techniques can be either pre- or post-synthetic and include using hard or soft structural template agents, defect formation, routes involving supercritical CO2, and 3D printing. We also discuss potential applications and some of the challenges involved with current techniques, which must be addressed if any of these approaches are to be taken forward for industrial applications.

Recent progress in strategies for preparation of metal-organic frameworks and their hybrids with different dimensions

Chemical Synthesis, 2023

As a new kind of organic-inorganic hybrid porous material, metal-organic frameworks (MOFs) exhibit a wide application prospect in gas storage and separation, catalysis and sensing due to their characteristics of large specific surface area, high porosity and coordination unsaturation. As more and more types of MOFs were reported, the synthetic strategies of MOFs-based materials have become a hot research topic. According to the morphological dimension, MOFs can be roughly divided into one-dimensional, two-dimensional and threedimensional structures. Herein, we summarize the synthetic methods and principles of MOFs from multidimensional perspectives, and explore the growth mechanism of MOFs with different morphologies based on dynamic and thermodynamic tuning. Finally, based on the above summaries, the challenges and opportunities of MOFs in the future are discussed.

Metal-Organic Frameworks (MOFs): Recent Advances in Synthetic Methodologies and Some Applications

Chemical Methodologies, 2019

The pursuit of rapid development in the area of catalysis, solar energy, environmental remediation, wastewater treatment and other aspects of ecological and sustainable chemistry has prompted substantial research by material chemists, physicists, academics and other scientists for the development of porous material. A lot of energy had been invested in this course by scientist, research organizations and public sector agencies from antiquity, but the resulting solution has been somewhat undesirable until two decades ago when Metal-Organic Frameworks (MOFs) appears to offer a glimpse of solution to those challenging issues. The adaptability, flexibility, uniqueness and usability of the metal-organic frameworks material, and its suitability to every facet of scientific and technological advancement has since triggered an incredible upsurge in studies aimed at uncovering more of the inherent influential properties of the materials, and its improvement for the betterment of material science and research world.

Metal Organic Frameworks: From Structure to Property

2016

Author(s): Bu, Fei | Advisor(s): Feng, Pingyun | Abstract: Porous Materials are an important class of materials due to their large-scale industrial applications in gas adsorption, gas separation, heterogeneous catalysis and so on. Among many kinds of porous materials, metal organic frameworks (MOFs) have emerged as one of the favorites in the past fifteen years. MOFs are crystalline porous materials that are mainly made of inorganic metal containing units (secondary building units, also called SBUs), organic ligands and templates.Compared to commercial inorganic porous materials, zeolites, which are based on Al3+ and Si4+, MOFs can accommodate most types of metal ions and a large number of organic ligands. This makes it possible for MOFs to adopt some fantastic features: (1) in principle the pore size and the surface area of MOFs can be tuned by changing the organic linkers, which allows MOFs to have a wider range of pore size and surface area than zeolites; (2) functionality can be...

A Review on Metal- Organic Frameworks (MOFS), Synthesis, Activation, Characterisation, and Application

Oriental Journal Of Chemistry

A myriad of MOFs reported in the literature are made up of transition metal ions (nodes), single or in clusters, braced by organic supports or ligands. But there are other MOFs in which the central metal are non-transition elements. MOFs are prepared by the combination of inorganic and organic building units to give materials with high porosity, and other unique properties. Due to MOFs unique structural topographies, they find applications in diverse areas such as gas adsorption, gas purification and separation, catalysis, and in drug delivery. In this review article, the design and methods for MOFs synthesis, MOFs- activation, characterization, as well as organic linkers used for the making of MOFs are discussed. Furthermore the shortage of MOFs research based on silicon-containing aryl building units as well as boron-containing building units in comparison to carbon-containing building units are highlighted. We hope that this review will help researchers, industrialists and academ...
