Zinc–air batteries (ZABs) hold potential as clean, cost‐effective, and sustainable energy storage system for the next generation. However, the application of ZABs remains challenging because of their poor rechargeability and low efficiency . The design of efficient bifunctional catalysts toward oxygen reduction reaction (ORR) during discharging and the oxygen evolution reaction (OER) during charging is essential to developing rechargeable ZABs. Transition metal (TM)‐doped carbon (TM‐C) materials stand out from all the available bifunctional catalysts due to the excellent specific surface area, diverse morphological structures , and the multiple metal active sites formed after TM doping. This paper, therefore, focuses on the synthesis, electrochemical properties, and potential mechanism of TM‐C catalysts. To make a novelty and logical statement, the voltage difference (ΔE = Ei = 10 − E1/2) between the ORR/OER catalytic process is employed to categorize different TM‐C catalysts reported in recent years, which are divided into two groups: I (ΔE = 0.7 − 0.9 V) and II (ΔE = 0.5 − 0.7 V). The catalytic mechanisms of bifunctional catalysts are clarified. More ways and ideas for synthesizing high‐performance bifunctional TM‐C catalysts are also provided. Finally, the current problem and prospects of this group materials are presented.

Metal−organic frameworks (MOFs) are an emerging material with a high specific surface area, desired morphology, and tunable pore size. However, MOFs suffer due to low electrical conductivity. Transition-metal sulfides are excellent supercapacitor materials because of their large storage capacity and electrical conductivity. To preserve a high surface area and obtain high electrical conductivity, Zn-MOF is directly grown on Ni-foam, and its surface is modified through various sulfurizing agents. The asfabricated Zn-MOF on Ni-foam exhibits a vertically oriented triangular rod-like morphology. Banana blossom, fiber, and rod-like morphologies are obtained due to the surface etching and surface sulfurization process by sulfurizing agents thioacetamide (TAA), sulfur (S), and thiourea (TU), respectively. The role of iR compensation in cyclic voltammetry analysis with higher mass-loading electrodes is established. The variations in its charge storage mechanism and charge-transfer kinetics corresponding to various sulfurizing agents are examined. Compared to other commonly used sulfurizing agents, TAA-assisted surface-sulfurized Zn-MOF provided excellent charge storage performance. It exhibits a maximum areal capacity of 4484 mC cm −2 (specific capacity of 747.3 C g −1 ) at a current density of 10 mA cm −2 . The asfabricated aqueous hybrid supercapacitor device exhibits a maximum specific energy of 77.8 W h kg −1 at a specific power of 0.73 kW kg −1 , even with a higher mass loading of 12.2 mg. The role and importance of mass loading are described by using an expanded Ragone plot.

“…MOFs are emerging crystalline porous nanomaterials, composed of metal ions and organic linkers. , Undistorted structures of MOF-derived materials have gained significant attention in recent years due to their potential for constructing functional materials. These materials offer advantages such as a large surface area, tunable porosity, and controllable structures. ,, MOF-based composites find applications in diverse fields including energy storage and conversion devices, gas separation, sensing, and water purification. − Among various MOF-based conductive carbonaceous materials, we prepared Fe-MOF-derived Fe 3 C-integrated electrospun porous carbon nanofibers (EPCNFs) mats. More importantly, as a negative electrode material, the Fe-MOF-derived porous carbon inside and outside of the EPCNFs effectively enhanced the charge storage.…”

Moderated thermal transformation of metal–organic frameworks (MOFs) empowers the synthesis of nanomaterials with precisely controlled porosities and morphologies, leading to enhanced performance in energy storage applications. Herein, we prepared MIL-88A-derived Fe3C-integrated EPCNFs (EPCNFs = electrospun porous carbon nanofibers) mats for the outside growth of Fe-MOFs using a moderated temperature calcination technique. The applied technique endorsed the conversion of the Fe-MOFs into Fe2O3/NPC (NPC = nanoporous carbon) without any destruction in the morphology of the nanorods. The integrated MIL-88A-derived Fe3C reduces the intrinsic resistance and synergizes with the overall performance of the resulting negative electrode (Fe2O3/NPC@Fe3C/EPCNFs). The resulting MOF-derived electrode materials have excellent performance within the −1 to 0 window potential range. The optimized electrode Fe2O3/NPC-350@Fe3C/EPCNFs exhibits a high specific capacitance (531 F g–1 at 1 A g–1) and stable cycling performance, retaining more than 90% even after 20000 cycles. The uniform, vertical, porous, and highly interconnected tetragonal rod-like nanomaterials can also maintain structural integrity during continuous charge/discharge. In addition, the assembled symmetric supercapacitor (Fe2O3/NPC-350@Fe3C/EPCNFs//Fe2O3/NPC-350@Fe3C/EPCNFs) exhibits an energy density of 21.6 W h kg–1 at a power density of 499.05 W kg–1 with superior cycling stability (20000 cycles at 20 A g–1), indicating the feasibility of the prepared electrode for practical application in energy storage systems.
