“…Metal-organic frameworks (MOFs)-crystalline coordination network lattices of metal cation nodes linked with organic ligands-are highly-tunable porous architectures, 1,2 whose versatile chemistry has led to their exploitation in a number of elds. These include catalysis, [3][4][5][6][7] gas adsorption and separation, 8-10 molecular sieving, 11 and water treatment, 12,13 amongst others. 14,15 Despite such versatility and exceptional porosity (up to 90% of its free volume), MOFs inherently suffer from low electrical conductivity.…”

“…Compared to their lower-dimensional counterparts, MOFderived 3D nanostructures exhibit unique characteristics, such as high mechanical reliability, high practicality, and easy largescale production. 47 By the pyrolysis of the MOF precursors, MOF-derived 3D nanostructures can be formed with chemically and morphologically desirable functionalities. Threedimensional nanostructures, such as carbon aerogels, nanoarrays, and gradient monoliths, have been realized through controllable strategies.…”

Metrics & MoreArticle Recommendations CONSPECTUS: Nanoporous carbon (NPC) materials with various architectures have attracted considerable attention because of their distinctive properties and great application potential in environmental remediation, energy conversion and storage, advanced sensors, and other applications. Traditional methods for the synthesis of NPCs, for example, the pyrolysis of natural products or polymers, template-assisted synthesis, and using deep-eutectic solvents, always involve toxic precursors and complex procedures, which greatly hinder further applications. Therefore, it is highly desirable to explore simple and feasible ways to prepare NPCs. Furthermore, to improve the performance and extend the application fields of NPCs, efficient strategies should be developed to regulate the components at the atomic level and construct multidimensional architectures. Metal−organic frameworks (MOFs, also known as porous coordination polymers), which consist of metal ions or clusters and organic ligands, are a new class of porous hybrid materials with reticular structures. As a result, MOFs show interesting characteristics, such as large surface areas, tailored compositions, and structural diversity, which make them ideal platforms for creating functional NPCs. Although significant progress has been made in MOF-derived NPCs with different architectures since the first reported MOF-derived NPC in 2008, this is still an emerging field with inexhaustible potential.In this Account, we highlight the concepts and strategies of our research on MOF-derived NPCs with different architectures, including zero-dimensional (0D) nanopolyhedral, core−shell, and hollow structures, one-dimensional (1D) nanofibers and nanotubes, two-dimensional (2D) nanoflakes and graphene nanomeshes, and three-dimensional (3D) nanoarrays, carbon aerogels, and gradient monoliths. First, we briefly introduce the history of MOFs and discuss their advantages as a platform for the preparation of NPCs. We then summarize the methods for the synthesis of 0D−3D NPCs from MOFs with controllable morphology, composition, and structure. Commonly, two major preparation concepts are involved: direct carbonation of MOFs and pyrolysis of MOF composites. For MOF composites, we have developed (i) electrospinning, (ii) in situ growth, (iii) freeze-drying, and (iv) chemical vapor deposition synthetic strategies for the generation of novel hybrid materials. Additionally, we describe the conversion mechanisms and how to precisely control the architectures in detail. The relationship between the chemical and physical properties of the parent MOFs and derived NPCs is also discussed. The potential applications of MOF-derived NPCs in energy, environmental, and catalysis fields are also demonstrated. Finally, the prospects and challenges for using MOFs as a precursor for designing NPCs are discussed. We believe that this Account will accelerate the development of MOF-derived NPCs and inspire the design and preparation of novel carbon materials.

“…Metal-organic frameworks (MOFs) are a family of porous crystalline materials composed of inorganic metal ions or metal clusters connected by organic ligands via coordination bonds [23,24]. Thanks to the advantages of high surface area, regular and highly tunable pore structure, and functional surface groups, MOF-based membranes are regarded as a superior candidate for liquid separation [25].…”

Membrane-based nanotechnology possesses high separation efficiency, low economic and energy consumption, continuous operation modes and environmental benefits, and has been utilized in various separation fields. Two-dimensional nanomaterials (2DNMs) with unique atomic thickness have rapidly emerged as ideal building blocks to develop high-performance separation membranes. By rationally tailoring and precisely controlling the nanochannels and/or nanoporous apertures of 2DNMs, 2DNM-based membranes are capable of exhibiting unprecedentedly high permeation and selectivity properties. In this review, the latest breakthroughs in using 2DNM-based membranes as nanosheets and laminar membranes are summarized, including their fabrication, structure design, transport behavior, separation mechanisms, and applications in liquid separations. Examples of advanced 2D material (graphene family, 2D TMDs, MXenes, metal–organic frameworks, and covalent organic framework nanosheets) membrane designs with remarkably perm-selective properties are highlighted. Additionally, the development of strategies used to functionalize membranes with 2DNMs are discussed. Finally, current technical challenges and emerging research directions of advancing 2DNM membranes for liquid separation are shared.
