Metal–Organic Framework Materials for Electrochemical Supercapacitors

Abstract

Exploring new materials with high stability and capacity is full of challenges in sustainable energy conversion and storage systems. Metal–organic frameworks (MOFs), as a new type of porous material, show the advantages of large specific surface area, high porosity, low density, and adjustable pore size, exhibiting a broad application prospect in the field of electrocatalytic reactions, batteries, particularly in the field of supercapacitors. This comprehensive review outlines the recent progress in synthetic methods and electrochemical performances of MOF materials, as well as their applications in supercapacitors. Additionally, the superiorities of MOFs-related materials are highlighted, while major challenges or opportunities for future research on them for electrochemical supercapacitors have been discussed and displayed, along with extensive experimental experiences.

Fabrication of amorphous Co/Mo–MnSex electrode materials for high-performance hybrid supercapacitors

“…They frequently include using polymetallic MOFs, MOF composites, and MOF derivatives as templates or precursors. 10,20 For example, Seo et al synthesized bimetallic Co/Mn-MOF nanoparticles by using a hydrothermal method that allowed the electrode material to acquire additional active sites from the synergistic action of the two metals. 21 4-Benzenedicarboxylic acid (BDC) has been employed as a ligand.…”

In Situ Growth of MOF-303 Membranes onto Porous Anodic Aluminum Oxide Substrates for Harvesting Salinity-Gradient Energy

“…3 In recent years, with the development of synthesis technology, the types of MOFs have become more and more abundant, showing broad application prospects in many fields, such as gas separation and storage, 4,5 ion-selective separation, 6,7 sensing, 8 catalysis, 9,10 proton conduction, 11 salinity-gradient energy (also known as osmotic or blue energy) conversion, 12 and supercapacitors. 13 As a newly discovered MOF material in recent years, MOF-303 (Al(OH)(HPDC), HPDC = 1H-pyrazole-3,5-dicarboxylate), which possesses the xhh topology formed by the connection of Al 3+ and the organic ligand HPDC, has attracted much attention due to its unique structural characteristics and performance. In detail, Al 3+ bridges with four carboxyl groups and shares the connection with two carboxyl groups under the action of its octahedral coordination characteristics, thereby realizing the connection between metal ions and organic ligands.…”

Highly Tunable MOF Luminophores Featuring Anthracene Directed Assembly and Fluorescence Regulation

“…Metal–organic frameworks (MOFs), featuring a highly modulable porous framework from the coordination assembly of metal ions and organic linkers, have developed as highly potential molecule-based materials in the recent decades. − The highly tunable structures and components of MOF have made it a versatile platform for the functions targeted construction of materials. Accordingly, MOFs have broad application prospects in many fields such as storage, − separation, − catalysis, , and biomedicine , due to their excellent physical/chemical properties. , However, owing to the complicated factors that will determine the assembly of the framework and the corresponding properties of the MOF, the illustration of the principles for the accurate assembly modulation and the corresponding properties tuning is still a challenging task. − …”
