“…Dai et al 28 had designed a bimetallic Ni-Fe MOF nanofiber by a facile solvothermal technique. The incorporation of TCPP(Fe) as a ligand had effectively promoted the movement of Li + and electrons, and the chelating interaction between Fe 3+ and porphyrin enhanced the cycle stability.…”

With the continuous growth of global energy demands and the increasingly serious environmental problems, the catalytic conversion and storage technology of sustainable energy has attracted more attention. Among the current energy storage methods, electrochemical energy storage (EES) is favored due to its high efficiency, stability, and environmental friendliness. In the development of EES devices, batteries and supercapacitors are the two most effective and attractive types. Metal−organic frameworks (MOF), as an emerging class of ordered crystal materials, are becoming highly promising electrode materials due to their adjustable topology structures, functionality, porosity, and electrocatalytic performances. The low conductivity seriously hinders the application of pristine MOFs in the field of energy storage, and a large number of MOF-based materials have been developed to meet the challenges of energy storage and conversion. Thus, the current review focuses mainly on the use of MOF-based materials (including pristine MOFs, MOF composites, and MOFderivatives) for EES, especially as electrode materials for metal-ion batteries and supercapacitors, and addresses the influence of material structures on electrochemical performances. Finally, we introduce the current challenges and improvement strategies of MOF-based electrode materials, pointing out the direction for developing electrode materials with industrial application value.

FeNi‐based layered double hydroxides (LDHs) are used as precursors to derive bimetallic FeNi‐metal organic frameworks (D‐FeNi MOFs) with terephthalic acid ligands, offering enhanced properties compared to conventionally prepared FeNi‐MOFs (C‐FeNi MOFs). D‐FeNi MOFs exhibited superior structural, surface, and electrochemical features, confirmed by density functional theory (DFT) studies, which also predicted their catalytic mechanism. Band edge potential calculations through Mott–Schottky analysis revealed their favorable redox potential, enhanced charge transfer, and reduced recombination resistance, explaining their superior photocatalytic efficiency. D‐FeNi MOFs degraded 91% of rhodamine B (RhB) and 89% of Congo red (CR), outperforming C‐FeNi MOFs, which degraded 84% and 77%, respectively. These MOFs are incorporated (3, 5, and 7 wt%) into polysulfone (PSU) membranes to develop photocatalytic membranes. The 7 wt% membranes (FNM7) exhibited high water flux (54.4 L m−2h−1) and dye flux (≈51.1 and 41.6 L m−2h−1) with rejection rates of ≈88% and 90% for RhB and CR, significantly surpassing bare membranes. FNM7 demonstrated superior anti‐fouling and photocatalytic regeneration (12.9% RhB, 9.6% CR degradation under sunlight) across three cycles. DFT studies showed FeNi centers weaken dye molecule bonds, aiding degradation, while carboxyl groups in MOFs formed robust hydrogen bonds with PSU, ensuring no particle leaching. This highlights D‐FeNi MOF‐membranes as an efficient system for wastewater treatment.
