“…[306][307][308][309] LD MOFs with large surface area and tunable structure provide an avenue for the development of high-performance Zn-air batteries. It is well known that the lack of stable and effective OER and ORR bifunctional catalysts for air cathode is one of the main problems encountered by Zn-air batteries nowadays.…”

Low‐dimensional metal–organic frameworks (LD MOFs) have attracted increasing attention in recent years, which successfully combine the unique properties of MOFs, e.g., large surface area, tailorable structure, and uniform cavity, with the distinctive physical and chemical properties of LD nanomaterials, e.g., high aspect ratio, abundant accessible active sites, and flexibility. Significant progress has been made in the morphological and structural regulation of LD MOFs in recent years. It is still of great significance to further explore the synthetic principles and dimensional‐dependent properties of LD MOFs. In this review, recent progress in the synthesis of LD MOF‐based materials and their applications are summarized, with an emphasis on the distinctive advantages of LD MOFs over their bulk counterparties. First, the unique physical and chemical properties of LD MOF‐based materials are briefly introduced. Synthetic strategies of various LD MOFs, including 1D MOFs, 2D MOFs, and LD MOF‐based composites, as well as their derivatives, are then summarized. Furthermore, the potential applications of LD MOF‐based materials in catalysis, energy storage, gas adsorption and separation, and sensing are introduced. Finally, challenges and opportunities of this fascinating research field are proposed.

“…Exploring non‐noble metal catalysts with desired activity and stability to replace costly Pt‐based ones for the oxygen reduction reaction (ORR) has been a significant challenge,4,5 for the large‐scale commercialization of energy‐related devices, such as rechargeable metal–air batteries6–9 and fuel cells 10,11. Transition metals and their derivatives, including alloys,12,13 oxides,14–16 chalcogenides,17–20 phosphides,21–23 carbides,24–26 and nitrides27–29 have attracted researcher's widely attention because of their intrinsic electrochemical properties and low price. Although the fact that these alternatives were proven effectively, their electrocatalytic performances for the ORR need to be further improved in comparison to that of Pt‐based catalysts, and are not satisfactory to meet the practical requirements.…”

Rare earth doped materials with unique electronic ground state configurations are considered emerging alternatives to conventional Pt/C for the oxygen reduction reaction (ORR). Herein, gadolinium (Gd)‐induced valence structure engineering is, for the first, time investigated for enhanced oxygen electrocatalysis. The Gd2O3–Co heterostructure loaded on N‐doped graphene (Gd2O3–Co/NG) is constructed as the target catalyst via a facile sol–gel assisted strategy. This synthetic strategy allows Gd2O3–Co nanoparticles to distribute uniformly on an N‐graphene surface and form intimate Gd2O3/Co interface sites. Upon the introduction of Gd2O3, the ORR activity of Gd2O3–Co/NG is significantly increased compared with Co/NG, where the half‐wave potential (E1/2) of Gd2O3–Co/NG is 100 mV more positive than that of Co/NG and even close to commercial Pt/C. The density functional theory calculation and spectroscopic analysis demonstrate that, owing to intrinsic charge redistribution at the engineered interface of Gd2O3/Co, the coupled Gd2O3–Co can break the OOH*–OH* scaling relation and result in a good balance of OOH* and OH* binding on Gd2O3–Co surface. For practical application, a rechargeable Zn–air battery employing Gd2O3–Co/NG as an air–cathode achieves a large power density and excellent charge–discharge cycle stability.

“…Moreover, transition metal nitrides have the atomic structures in either fcc or hcp with the smaller nitrogen atoms occupying the interstitial sites, as those of metal or metal alloys, and thus often present some metal‐like properties . Both binary metal nitrides and ternary metal nitrides with two metal elements can exhibit a metal‐like behavior for ORR/OER catalysis and thus can be utilized for rechargeable metal–O 2 batteries . For example, Fu et al examined the electrochemical performances of a mesoporous ternary Ni–Fe nitride (Ni 3 FeN) material for rechargeable Zn–O 2 batteries ( Figure 11 a) .…”

For example, Fu et al examined the electrochemical performances of a mesoporous ternary Ni–Fe nitride (Ni 3 FeN) material for rechargeable Zn–O 2 batteries ( Figure 11 a) . Owing to the high electric conductivity of nitrides and the avoid use of carbon for possible carbon corrosion at high potentials, the Zn–O 2 battery showed an excellent cycling stability up to 300 cycles with a very small performance decay (<3.9%) together with a high OCV and low polarization (Figure b–d).…”

The success of Li–air/O2 batteries has brought extensive attention to the development of various promising non‐Li metal–O2 batteries, such as Zn–O2, Al–O2, Mg–O2 batteries, etc., which have exhibited unique advantages, such as low production cost, high energy density, and much enhanced safety. The versatile non‐Li metal–O2 batteries provide a better opportunity for meeting the practical requirements for sustainable energy supplies in various applications. A high‐performance cathode in non‐Li metal–O2 batteries that can effectively trigger both oxygen reduction and evolution reactions and thus boost the overall battery performance is of great research interest. In this article, a comprehensive review on the development of Li‐free metal–O2 batteries and particularly focusing on the oxygen catalytic cathodes for both primary and secondary non‐Li metal–O2 batteries is carefully performed. The current challenges and potential solutions are also outlined and proposed. Through carefully selecting and rationally designing promising catalytic cathodes, a series of non‐Li metal–oxygen batteries toward practical energy storage applications are highly anticipated.
