MXenes have potential applications in the field of supercapacitors. As a twodimensional material, how its structure, properties, and surface chemistry facilitate energy storage is discussed. A detailed analysis of the synthesis of MXenes and factors affecting energy storage in supercapacitor grounds is explained in detail. Possibilities of anode architecture to improve supercapacitor performance on industrial standards are discussed. This review will aid in planning better MXene hybrid anodes to assemble supercapacitors with desired electrochemical performance. Ways to improve capacitance, energy density, and voltage window of electrodes are explained based on literature reports. Electrochemical performance is evaluated by the effect of hierarchical structures, heterostructures, transition metal oxides, carbon compounds, polymers, and so on. Anode fabrication methods for modern micro-supercapacitors are also incorporated in this study. A good selection of electrolytes and fabrication techniques adapted for MXene-based anode fabrication is emphasized. This review will help in future options of supercapacitor anode designing.

“…Fe-based MOFs as the precursor or soft template for producing SCs electrodes can be categorized as three different types: 1) Fe-based metal oxides (Fe 3 O 4 or Fe 2 O 3 ) compositing with carbon materials; [93][94][95] 2) Fe-based carbide materials; [96,97] and 3) Fe-based bimetallic metal oxides. [98][99][100][101] As to type 1, in 2014, Meng and co-workers reported a porous Fe 3 O 4 /C material decomposed from the classic MIL-88B-Fe and documented this composite as the SCs electrode. [93] Within the potential window of À1 to 0 V, a maximum capacitance of 139 F g À1 was achieved at a current density of 0.5 A g À1 , displaying superior negative electrochemical behavior.…”

“…With the same strategy, Xie et al reported MOF-derived bimetallic CoFe 2 O 4 nanorods anchored in conductive Ti 3 C 2 T x (MXene) nanosheets, which delivered 88.2% after 10 000 charge/discharge cycles and an outstanding volumetric capacitance of 2467.6 F cm À3 in a neutral electrolyte (1 M LiCl). [99] Notably, utilizing polyoxometalates@MOFs (POMs@MOFs) as the precursors or templates to generate the SCs electrodes with more redox-active sites would be a frequently adopted methodology because POMs including a large family of homo/heterogeneous metal-oxide clusters possess reversible redox abilities with multiple electrons. [104][105][106] Zhang et al obtained the POM@Fe-MOF derived WO 2 @FeWO 4 electrode with a specific capacitance of 124 F g À1 at a current density of 0.5 A g À1 .…”

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.

“…A large volumetric capacitance of 2467.6 F cm −3 was achieved for the electrode, and the flexible symmetrical supercapacitor displayed a specific areal capacitance of 356.4 mF cm −2 . [ 108 ] Indium‐doped tin oxide (ITO) glass has also been chosen as substrate for the in situ growth of a hierarchical porous NiO film derived from MOF‐74, which was used as an efficient electrode material for a supercapacitor. [ 109 ] Because of the strong binding force between the two materials and the large surface areas, the electrode showed excellent cycling stability for 15 000 cycles.…”

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.
