“…The combination of a meso/microporous hierarchical structure of NPCs and high conductivity of the carbon nanofibers resulted in a very high value for gravimetric and volumetric capacitance of the NPCF electrode. Yang et al reported the fabrication of yolk–shell MnO x nanoparticles confined in carbonized nanofibers (ysMnO x @NC) for use as anode materials in lithium‐ion batteries (LIB) (Figure b). The electrospinning method was applied first to structure the MOF Mn‐BTC (Mn‐1,3,5‐trimesic acid) into a polymer nanofiber matrix with a “beads‐in‐string structure.” The MOF‐polymer composite nanofibers were then preoxidized in air at 300 °C, leading to Mn‐BTC nanospheres with a multishell structure, displaying distinct spherical envelopes with a “ring‐in‐ring” morphology (Figure c).…”

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...

Metal organic frameworks (MOFs) have been exploited for various applications in science and engineering due to the possibility of forming different mesoscopic frameworks and pore structures. To date, further development of MOFs for practical applications in areas such as energy storage and conversion have encountered tremendous challenge owing to the unitary porous structure (almost filled entirely with micropores) and conventional morphology (e.g., sphere, polyhedron, and rod shape). More recently, one-dimensional (1D) MOFs/nanofibers composites emerged as a new molecular system with highly engineered novel structures for tailored applications. In this mini-review, the recent progress in the development of MOFs-based 1D nanofibers via electrospinning will be elaborated. In particular, the promising applications and underlying molecular mechanism of electrospun MOF-derived carbon nanofibers are primarily focused and analyzed here. This review is instrumental in providing certain guiding principles for the preparation and structural analysis of MOFs/electrospun nanofibers (M-NFs) composites and electrospun MOF-derived nanomaterials.

Designing carbon nanotubes (CNTs)-based materials are attracting great attention due to their fantastic properties and greater performance. Herein, a new CNTs network triggered by metal catalysts (e.g., Co, Ni, or Cu) is constructed on metal oxide (e.g., MnO) microparticles, giving rise to a high-performance Co-MnO@C-CNTs anode in lithium-ion batteries (LIBs). An extremely high capacity of 1050 mAh g −1 , extraordinary rate capacities over 10 A g −1 , and a long lifespan over 500 cycles are demonstrated. The great features of Co-MnO@C-CNTs anode are further confirmed in LIBs when the nickel-rich cathode (e.g., LiNi 0.8 Co 0.1 Mn 0.1 O 2 ) is used and charged at a high voltage over 4.5 V. A high-capacity retention of 71.5% can be maintained at 1 C over 150 cycles. The superior performance relates to the CNTs network, which not only acts as an "expressway network" for fast ion/electron transportation but also buffers structural variation. Moreover, the metal nanoparticles can also enhance the electrical conductivity and catalyze the (de-)lithiation of metal oxide, resulting in higher reversibility and long-term cyclability. This study opens a new avenue to prepare CNTs-based functional materials and also explores the potential applications of metal oxide-based anode for high-performance batteries.
