“…In the FT‐IR spectrum of ZIF@MIL, the strong absorption peak at ν=3400 cm −1 can be attributed to adsorbed water. Two peaks at ν=1620 and 1370 cm −1 can be ascribed −COO − vibrations in BTC, indicating that BTC successfully grew on the outer surface of ZIF‐67 [25] . Two further peaks at ν=2930 and 3140 cm −1 can be ascribed to C−H vibrations and a peak at 1580 cm −1 can be attributed to the C=N vibration in imidazole.…”

Although metal‐organic frameworks have proven to be excellent electrocatalytic materials, their application as electrode materials remains limited. The preparation of heterostructures is considered an effective method to improve catalytic activity. Herein, we describe the design and assembly of a dual‐MOF heterostructure (CoNi−ZIF‐67@Fe−MIL‐100, denoted ZIF@MIL). Specifically, we grew a layer of MIL‐100 in situ on a bimetallic ZIF‐67 surface using a solvothermal method. We demonstrate that the ZIF@MIL has remarkable OER electrocatalytic performance, requiring a low overpotential and showing a small Tafel slope, compared to pure ZIF‐67 and MIL‐100 in 1.0 m KOH. More importantly, it has excellent operational durability for 50 h at 100 mA cm−2. The high catalytic activity of ZIF@MIL can be attributed to the heterostructure that can expose more active sites, the synergistic effect between ZIF‐67 and MIL‐100, and improvement of electron transfer ability. Our work provides a new way to design and prepare dual‐MOF crystals with different structures as electrocatalysts.

“…115 Additionally, Pourfarzad et al applied a CES method for the fabrication of a mixed MOF, Ni/Fe-BTC, using nickel chloride and iron chloride as Ni( ii ) and Fe( ii ) sources, and BTC as the linker. 116 Surprisingly, zinc–air batteries with the Ni/Fe-BTC-MOF illustrated a significant cycling-life of 5262 h@10 mA cm −2 with an energy density of 1082 W h kg Zn −1 . Similarly, Li et al applied a bimetallic synergy strategy to attain bifunctional electrocatalysis for flexible rechargeable Zn–air batteries.…”

“…In another study, Ni/Fe-BTC MOF nanorods were electrochemically prepared via utilizing a two-electrode system containing Ni(II) and Fe(II) chlorides, and BTC linker [177]. When the Ni/Fe-BTC MOF was applied as a cathode in Zn-air batteries, the excellent cycle stability for 5262 cycles (over 594 h) with round trip efficiency (65.80%) at a current density of 10 mA cm −2 was delivered.…”

Metal–organic framework (MOF)-based materials with high porosity, tunable compositions, diverse structures, and versatile functionalities provide great scope for next-generation rechargeable battery applications. Herein, this review summarizes recent advances in pristine MOFs, MOF composites, MOF derivatives, and MOF composite derivatives for high-performance sodium-ion batteries, potassium-ion batteries, Zn-ion batteries, lithium–sulfur batteries, lithium–oxygen batteries, and Zn–air batteries in which the unique roles of MOFs as electrodes, separators, and even electrolyte are highlighted. Furthermore, through the discussion of MOF-based materials in each battery system, the key principles for controllable synthesis of diverse MOF-based materials and electrochemical performance improvement mechanisms are discussed in detail. Finally, the major challenges and perspectives of MOFs are also proposed for next-generation battery applications.
