“…Compared with traditional inorganic porous materials, conductive MOFs possess higher porosity, larger specific surface areas, diverse structures, and excellent performance. [86] The types and ratios of central metal ions and ligands can be adjusted to directly control the structure and properties of conductive MOFs. In particular, among the conductive MOFs, two-dimensional (2D) conductive MOFs are one of the hotspots studies in recent years.…”

Supercapacitors possess important prospects in power supply, owing to the characteristics of fast charging/discharging and long cycling life. As emerging materials, metal-organic frameworks (MOFs) are the cutting-edge electrode active materials for supercapacitors due to their good conductivity, tunable pore structure, as well as diverse composition. In this Minireview, we summarize the recent progress in MOF electrodes for supercapacitors. We focus on the synthesis of intrinsically conductive MOFs constructed from different organic linkers and adjustable metal ions, and the preparation of conductive MOF composites hybridized with conducting materials (conducting polymers and carbons). Following the discussion of both different types of conductive MOFs and their composites in supercapacitors, the challenges, and opportunities of conductive MOF electrodes for supercapacitors are further prospected at the end of this contribution, which would provide some valuable insights in facilitating the use of MOF materials in energy-storage applications.

“…The ligands of polyamine and polyphenol (Figure 9) are also popularly used to construct 2D Ni‐MOFs ( 117 ‐ 127 , 134 ‐ 138 ) in recent years 78,93,145‐151,157 . In addition to the common properties of ultrahigh surface areas and larger interior layer‐spaces and so forth, these sheet‐like 2D materials deliver versatile performances owing to their distinctive inner structures and compositions 57 . Wu and coworkers prepared MSCs by using Ni‐CAT MOF ( 117 ) to grow selectively on patterned 3D laser‐scribed graphene (LSG) electrodes through a combined laser‐scribing and a selective solvothermal deposition process (Figure 10A).…”

“…As shown in Figure 2B, the metal‐organic compounds can be divided into molecular complexes and metal coordination polymers, and typical structures of metal coordination polymers of different dimensions are demonstrated. It is worth noting that a previous paper has reviewed the MOFs of different spatial dimensions and their application in the SC field, and thus this paper would not focus on the dimension effect of the metal‐organic compounds on the SC performance 57 . The metallation of the organic SC‐electrode materials tends to bring about better performances due to the following factors: (a) The metallation helps generate extra redox activities by charge transport of both the metal atoms and the organic ligands.…”

In this review, both SC electrodes and device performances of monometallic and bimetallic metal‐organic compounds from the first transition metal series and their composites were comprehensively summarized for the first time.…”

Metal‐organic compounds, including molecular complexes and coordination polymers, have attracted much attention as electrode materials in supercapacitors owing to their large surface area, high porosity, tailorable pore size, controllable structure, good electrochemical reversibility, and abundant active sites. Among the variety of metal‐organic compounds exhibiting desired supercapacitor performances (high specific capacitance, long cycling life, high energy density, and power density), those with metals in the first transition metal series are the most studied due to their rich covalent states, light atom weight, environmental‐friendliness, non‐toxicity, and low cost. In this review, the recent reports on the metal‐organic compounds of the first transition metal series as electrode materials in supercapacitors are summarized and their electrode and device performances are discussed in terms of different metal elements and typical multidentate ligands. Moreover, the current challenges, design strategies, future opportunities and further research directions are also highlighted for metal‐organic compounds in the field of supercapacitors.

Metal-organic frameworks (MOFs) are deemed an attractive type of active material during electrochemical reaction processes because of their unique compositional and structural superiority, as well as the dual role as both templates and precursors to derive a large variety of functional materials for energy conversation and storage. Herein, reviewing the recent advances of MOFs and their derived functional materials as electrode materials in supercapacitors, which are classified into pristine MOFs, MOF composites, and MOF-derived functional materials, is focused on. Their synthetic routes and modification strategies are summarized and the relationship between the diversity of the architectures and compositions of MOF-based materials and their electrochemical performance is discussed. In addition, the challenges and opportunities on future research and extensive applications of MOFs and their derived functional materials are offered.
