“…By varying metal ions/organic linkers, along with the original versatile characters of MOFs including high surface area, controllable structure, ordered, meso‐ or microporous, and tunable pore, the specific characteristics of functional MOFs can be fully brought into many applications in the area of electrochemistry, such as LIBs and Li–S batteries, supercapacitor, proton conductor, electrocatalysis (HER, ORR, small organic molecules, or pollution molecules), electrochemical sensor. First, many efforts have been made to improve the conductivity of MOFs by a variety of methods, such as adopting metal center or mixed metal units with redox activity or organic linkers with reactive activity for pristine MOFs or fabricating MOF composites containing various conductive materials@MOF, such as metal, metal oxide, different carbon materials, LDH sheet, or conductive plates.

“…In principle, MOFs are able to be designed and fabricated at the molecular level because of their tunable chemical compositions. Although it is still difficult for the accurate prediction and control of the overall topological structures, the redox‐active metal centers, ligands, along with the building blocks featuring electron‐donating and electron‐accepting ability, can be rationally introduced into MOFs, thus endow MOFs with electrochemical applications . The functional surface area and high porosities of MOFs play crucial role in many functional properties including proton conduction, supercapacitors, and Li‐based batteries.…”

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 ...

View full text Add to dashboard Cite

Recent developments in supercapacitor technology in terms of materials and devices are reviewed herein. Beyond the conventional materials (i. e., carbonaceous matters, metallic compounds and conducting polymers), various multifunctional materials are reported in literature as future supercapacitive materials. A comprehensive account on such materials is lacking due to the diversified electrochemical characteristics of these materials. In this review, we bring all such non‐conventional multifunctional energy storage materials under a same umbrella for summarizing the recent advancements in supercapacitors. The envisaged multifunctional materials include metal‐organic‐frameworks (MOFs), covalent‐organic‐frameworks (COFs), heteroatom‐doped carbonaceous materials, biomass‐derived porous carbons, black phosphorous, mixed conductors, perovskite nanoparticles, polyoxometalates (POMs), redox active electrolytes, slurry materials for flow supercapacitors, thermal self‐charging materials, thermal self‐protective materials, piezoelectric materials and electrochromic materials. Inherent pros and cons of each class of material are discussed, and materials modifications towards the successful device fabrications are highlighted herewith. While the MOF‐based supercapacitors are drawing some attentions, other non‐conventional energy storage materials are truly in the nascent stage of developments. This review culminates with summary and proposed future directions for product developments. In brief, this article provides a holistic view regarding all non‐conventional multifunctional energy storage materials for future supercapacitor technology.

Flexible Solid PANI Fiber Networks/Ni‐MOF@CC Electrodes for High‐Performance Capacitors: Synthesis and Stability Study

et al. 2020

In this work, the nickel‐based metal organic framework (Ni‐MOF) is attached to the conductive carbon cloth (CC) by using a hydrothermal reaction. In order to make MOFs strongly interacted with CC, polymeric molecules of polyaniline (PANI) are deposited on Ni‐MOF@CC employing an in–situ polymerization method. The PANI shows a three‐dimensional fiber‐network morphology. Due to the improved electrical conductivity and the porous networks, the electrochemistry property of the obtained flexible PANI/Ni‐MOF@CC is greatly enhanced compared with Ni‐MOF@CC. The specific capacitance of PANI/Ni‐MOF@CC reaches 109 F cm−2 (573 F g−1). The optimum energy density of PANI/Ni‐MOF@CC at 0.1 A cm−2 can be 7 mWh cm−2 with power density of 70 mW cm−2. Because the fiber networks of PANI on MOF enhances the interactions between MOF and CC, the PANI/Ni‐MOF@CC shows high stability of 95 % capacitance retention after 5000 charge‐discharge cycling.
