Layered structural Co-MOF nanosheets were synthesized and then used as an electrode material for supercapacitors for the first time. This material exhibited a high specific capacitance, a good rate capability, and an excellent cycling stability. A maximum capacitance of 2564 F g can be achieved at a current density of 1 Ag . Moreover, the capacitance retention can be kept at 95.8 % respectively of its initial value after 3000 cycles. To the best of our knowledge, both the specific capacitance and the capacitance retention were the highest values reported for MOF materials as supercapacitor electrodes until now. Such a high supercapacitive performance might be attributed to the intrinsic characteristics of this kind of Co-MOF material, including its layered structure, conductive network frame, and thin nanosheet.

“…CNT is another carbon material used to improve the conductivity of the MOF composites. Lin and co‐workers synthesized a composite material of CNTs and Mn‐MOF (Mn(C 2 H 4 O 2 ) 2 (H 2 O) 4 ) . The incorporation of CNTs led to an enhanced capacitance from 43.2 F g −1 for pure Mn‐MOF to 203.1 F g −1 for the Mn‐MOF/CNT composite in 1 m Na 2 SO 4 .…”

Metal-organic frameworks (MOFs), a new class of crystalline porous organic-inorganic hybrid materials, have recently attracted increasing interest in the field of energy storage and conversion. Herein, recent progress of MOFs and MOF composites for energy storage and conversion applications, including photochemical and electrochemical fuel production (hydrogen production and CO reduction), water oxidation, supercapacitors, and Li-based batteries (Li-ion, Li-S, and Li-O batteries), is summarized. Typical development strategies (e.g., incorporation of active components, design of smart morphologies, and judicious selection of organic linkers and metal nodes) of MOFs and MOF composites for particular energy storage and conversion applications are highlighted. A broad overview of recent progress is provided, which will hopefully promote the future development of MOFs and MOF composites for advanced energy storage and conversion applications.

“…Nevertheless, most transition metals are unstable in acid media due to their corrosion. In this regard, the MOF@C composite is fabricated with various carbon materials (e.g., graphene, CNTs, carbon black, and hollow or porous carbon) or some polymeric materials (e.g., polyaniline (PANI) and polypyrrole) adopted into MOFs . This C family has been studied for the electrode and catalyst supports ascribed to their high specific surface area, high conductivity, and effective charge transfer at the electrodes.…”

“…Hence, CNTs also have wide applications in electronic devices and sensors. The introduction of CNTs into Mn‐MOF (Mn(C 2 H 3 O 2 ) 2 (H 2 O) 4 ) can form CNTs@Mn‐MOF composite, thus resulting in the enhancement of electroconductibility and the specific capacitance from 43.2 F g −1 for pure Mn‐MOF. Moreover, such a CNTs@Mn‐MOF composite exhibits outstanding stability and power density, in which 88% retention capacitance of the initial one can be kept even after 3000 cycles.…”

“…The functional surface area and high porosities of MOFs play crucial role in many functional properties including proton conduction, supercapacitors, and Li‐based batteries. Furthermore, the development of MOF composites by introducing new electrochemical materials into pristine MOFs enhances the MOF conductivity and boosts the electrochemical applications of MOFs. The implantation of functional materials into the MOF pores further broadens the applications of MOFs and improves the cycling performance.…”

metal-oxo units) coordinating with electron-donating organic ligands. These hybrid materials have received broad concern because MOFs can be rationally synthesized with high porosities, large internal surface areas, uniform but adjustable pore sizes and structures. MOFs exhibit a tremendous growth, in terms of numerous structures, fascinating topological nets, and various application including gas storage and separation, [9][10][11][12][13][14][15][16][17][18][19][20][21] catalysis, [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] sensor, [38][39][40][41] drug delivery, [42,43] luminescence, [44,45] and others. [46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] Apart from these applications, in recent years, there is an increasing interest in discovering the electrochemical applications in the field of supercapacitors, batteries and fuel cells, hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR), electrochemical decomposition of highly oxidizing and toxic compounds, electrochemical sensors, etc.In view of the ever-growing energy demand as well as the increasing serious environmental crisis caused by the combustion of traditional fossil fuels, the pursuit of renewable energy sources resorting to the sunshine and wind, along with storage technologies, has always been a hot research subject. The intermittent feature of solar and wind sources limits their applied range, thus the effective energy storage technology is becoming a tremendous need to put electronic equipment into operation and provide electrical transportation power for commuters. Energy storage resorting to electrochemistry is thought to be one of the most promising candidates for energy storage. MOFs possess their particular advantages, in comparison with other types of porous materials including active carbon, zeolites. By selecting different metal ions and organic bridging linkers, MOFs constructed can meet the requirements of particular application through the predesign and postsynthesis methods. Various MOFs and MOF composites have been successfully used in the electrochemical areas. Moreover, MOFs as the sacrificial materials have been converted to various nanostructures, such as porous carbon, metal nanoparticles, metal oxides, and their composites with different treatments. These nanostructures with the maximum exposure of active sites inherit high surface area of MOF precursors to some extent and exhibit good performance as electrodes. For MOF-derived nanoporous functional materials, a number of reviews [61][62][63][64][65][66][67] and reports [68][69][70][71][72][73][74][75][76][77][78][79][80][81] have been published, which provided As a youthful family of crystalline porous materials, metal-organic frameworks (MOFs), assembled by inorganic vertices (metal ions or clusters) and organic ligands, feature ultrahigh porosity, high surface area, and synthetic and structural tailorability, along with relatively easy synthesis, making them excellent candidates for a large ...
