“…Recent studies highlight the ability of the organic linkers or the metal ions at the MOF nodes to undergo 1 À e À oxidations [1][2][3] or reductions, [4][5][6] for the MOFs themselves to serve as conductive materials [6][7][8][9][10][11][12] or semiconductors, [13][14][15][16] and for the MOFs to facilitate redox reactions that are pertinent to fuel cells and energy. 3,[17][18][19][20][21][22][23] MOFs are also already commercially available in Li-ion batteries. [24][25][26][27] The diversity of these studies reaffirms the promise of using MOFs in a variety of redox systems.…”

organic linkers with a periodic, nanoscaled structure and ultrahigh surface areas. With their tunable pore/cage sizes, flexible skeleton, and large surface-to-volume ratio, [13][14][15][16][17][18][19] MOFs have a large potential for a wide range of applications, including gas storage and separation, rechargeable batteries, supercapacitors, solar cells, nanoreactors, heterogeneous catalysis, or drug delivery. [20][21][22][23][24][25][26][27] Recently, significant efforts have been devoted to the design and synthesis of new MOFs structures and the investigation of their physical or chemical properties. MOFs are generally prepared as bulk form through traditional hydrothermal or solvothermal synthesis. [28][29][30][31] In order to expand the application range, suitable pathways for the structuring of MOF powders into a functional architecture or devices are highly desirable.Currently, intensive efforts are focusing on the structuring of MOFs at the mesoscopic/macroscopic scale for the use as coatings, membranes, or sophisticated architectures in specific devices and applications. [32][33][34][35] A major difference in the structuring of MOFs into complex shapes compared to inorganic microporous materials, such as zeolites or silica, is the fact that most inorganic binders cannot be used for MOFs as these binders usually require heat treatment. The intrinsic fragility of MOFs needs to be considered which is related to the inorganic/organic hybrid character of this class of materials and the resulting limited thermal and mechanical stability. Alternatively, a more effective way to structure MOFs is the combination with polymer materials. The polymer which acts as a binder improves the mechanical flexibility and ensures chemical stability. Numerous methods have been developed for structuring MOF-polymer compositions including hard or soft templates, spin-or dip-coating, spray-drying, printing, or lithography approaches. [36][37][38] The integration of MOFs into a polymer matrix can result in poor MOF-polymer dispersion and compatibility issues owing to the different physical and chemical properties for the two kinds of materials and this is a challenge in some applications, e.g., in MOF-based mixed matrix membranes for gas separation. [39][40][41][42] The poor interfacial compatibility would lead to agglomeration of MOF particles, causing the formation of nonselective voids between the MOFs particles and the polymer.Electrospinning is a fabrication method to produce continuous ultrafine fibers with diameters in the range of a few tens of nanometers to a few micrometers in the form of nonwoven mats, yarns, etc. The mechanism of electrospinning is based Herein, recent developments of metal-organic frameworks (MOFs) structured into nanofibers by electrospinning are summarized, including the fabrication, post-treatment via pyrolysis, properties, and use of the resulting MOF nanofiber architectures. The fabrication and post-treatment of the MOF nanofiber architectures are described systematically by two routes: i) the dire...

Ultrasound (US) technology is already into the research field providing a powerful tool of producing nanomaterials or being implicated in decoration procedures of catalyst supports for energy applications and material production. Toward this concept, low or/and high-frequency USs are used for the production of nanoparticles, the decoration of catalytic supported powders (carbon-based, titania, and alumina) with nanoparticles, and the production of metal-organic frameworks (MOFs). MOFs are porous, crystalline materials, which consist of metal centers and organic linkers. Those structures demonstrate high surface area, open metal sites, and large void space. All the above produced materials are used in heterogeneous catalysis, electrocatalysis, photocatalysis, and energy storage. Batteries and fuel cells are popular systems for electrochemical energy storage, and significant progress has been made in nanostructured energy materials in order to improve these storage devices. Nanomaterials have shown favorable properties, such as enhanced kinetics and better efficiency as catalysts for the oxygen reduction reaction (ORR).
