“…[132][133][134] By virtue of abundant active sites, multicenter systems, and numerous inner spaces, these layered materials have been extensively studied as SCs electrodes. [135][136][137][138][139][140] In 2016, Qu and co-workers utilized three functionalized BDC linkers separately as layer linkers and 1,4-diazabicyclo[2.2.2]octane (DABCO) as pillar ligand co-reacting with Ni ions to construct several pillar-layered Ni-MOF-based electrode materials. [80] The electrode with superior structural ability under humid surroundings, namely, Ni-DMOF-ADC, delivered 552 F g À1 at 1 A g À1 and maintained excellent capacitance retention of 98% after 16 000 cycles at a high current density of 10 A g À1 (Figure 4a).…”

Iron‐series (Fe, Co, and Ni) containing metal–organic frameworks (MOFs) have gained great concern in supercapacitors (SCs) because of their tailorable architectures, multiple redox‐active sites, and intriguing properties. Given the importance of porosities in MOFs for charge transmission, an essential assessment of their designs, preparation methods, and engineering technologies is strongly required to further explore and optimize SCs. Through empowering conductive backbones and redox‐active centers, iron‐series containing MOF‐based electrodes have made outstanding achievements recently. This review aims to summarize these core reports on iron‐series containing MOFs. Correspondingly, the design strategy, the reason for compositing, the strategy of introducing heteroatoms, and the current divergences on structural alteration mechanisms are discussed. Potential bottleneck issues and coping strategies are also perspectively discussed to guide future optimization.

“…The electrodes and SC performances of manganese‐organic compounds are summarized in Tables 1 and 2. MOFs with polycarboxylate ligands (Figure 4A), which generally exhibit 2D or 3D layered structures with [M m (COO) n ] nodes of paddle‐wheel secondary building units and π‐conjugated bridging ligands (Figure 4B), 73,97 have aroused wide research interest as electrode materials for SCs. To the best of our knowledge, nearly all reported manganese‐organic compounds used as electrode materials for SCs are Mn‐MOFs with polycarboxylate ligands ( 1 ‐ 9 ) and the highest value of C g (1358 F g −1 ) was achieved by a polythreaded Mn‐MOF ( 5 ) based on the ligands of H 2 BDC and tipa 90 .…”

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.

“…[17] A binuclear Co-MOF constructed by Xiao et al has photocatalytic activity on RhB under UV irradia-tion. [18] The porous structure of MOFs enables active sites to be exposed to a greater extent, thus making the contact between reactants and active sites easier. MOFs have properties similar to semiconductors, so under the action of light, MOFs can produce electrons and holes, which can catalyze redox reaction.…”

A novel metal-organic framework [Zn0.5(L1)(4,4'-Bpy)0.5], (HU21, HU for Hohai University, L1 = 4-hydroxy-3-nitrobenzoic acid, 4,4'-bipyridine = 4,4'-Bpy), has been isolated through hydrothermal reaction. Single-crystal X-ray diffraction reveals the compound features a 1D fishbone-like chain. A fast adsorption rate of methylene blue with HU21 was observed in the dark, but under irritation the degradation rate of the dye was obviously increased. The degradation of methylene blue dye reached 248 mg/g under light irritation, and the photocatalytic activity reached 96.1%.
