Electrochemical energy storage systems with high power output, large energy density, and stable performance are urgently needed. Zn-air batteries are one of the most promising candidates owing to abundant and inexpensive resources used, decent energy density, and the high reduction potential of Zn. The most significant challenge of primary and rechargeable aqueous Zn-air batteries is the relatively high overpotential due to the sluggish kinetics of oxygen reactions on the air cathode. Highly efficient oxygen catalysts derived from metal-organic framework (MOF) precursors have demonstrated remarkable capabilities for facilitating the oxygen reactions. In this contribution, we review the recent progress in state-of-the-art MOF-derived materials for use as oxygen catalysts in primary and rechargeable Zn-air batteries. We first summarize the development of several important MOF derivatives, including transition metal-nitrogen-carbon (TMÀNÀC) composites, carbon-based transition metal compounds, and metal-free carbons. The advantages and disadvantages of these MOF-derived catalysts are also discussed. Strategies for optimization of the gas-liquid diffusion and the long-range electronic transportation on the air cathode with these MOF-derived catalysts are also demonstrated. Finally, the main challenges and some perspectives for developing advanced MOF-derived catalysts applied in Zn-air batteries are provided.

“…Wei et al prepared a Fe–N/C catalyst by confining Fe centers within cavities of rho ‐ZIF matrix (ZIF with the rho topology) without solution‐based steps or post‐ammonia/acid treatments. [ 166 ] The precursor of Fe‐TPP⊂ rho ‐ZIF (Fe‐TPP = tetraphenylporphyrin iron) was prepared by a one‐pot mechanochemical method, followed by pyrolysis (950 °C under N 2 ) to obtain the single‐atom catalyst with 3.8 wt% Fe content (Figure 14d). The porphyrin architecture contains a high number of nitrogen species, especially pyrrolic nitrogen sites, providing abundant opportunities to stabilize single‐atom Fe species.…”

“…Overall, single transitional metal atom catalysts are promising candidates to replace conventional Pt catalyst for catalyzing ORR and IrO 2 /RuO 2 catalyst for OER in Zn–air batteries because of the enhanced catalytic properties and comparatively lower production costs. Many kinds of SACMs based on different synthesis methods have been applied in air electrodes, including heteroatom doping, [ 93 ] surfactant assisting, [ 92 ] space confining, [ 166 ] element substituting, [ 169 ] and chemical vapor deposition. [ 175 ] Heteroatom doping and surfactant assisting methods are based on regulation of matrix materials, while space confining and element substituting methods focus on control and confinement of metal species.…”

power and energy densities are the imperative units for these cutting-edge energy harvesting and storage. [3] The state-ofthe-art commercial batteries are prepared with graphite anodes and lithium transition-metal oxide cathodes that reversibly intercalate lithium (Li) ions with moderate stability and energy densities. [4] The intrinsic physicochemical properties and ion insertion mechanisms of conventional materials limits the energy capacity of devices, which will not be quantified for unprecedented demand of modern electronics. [5] Other than the insertiontype electrode materials, there exist some conversion-type electrode materials with higher energy storage capability and faster electrochemical conversion dynamics, including transition-metal dichalcogenide (TMD) and silicon materials. [6] TMD materials demonstrate strong chemical interaction and high catalytic effect with active species in batteries, which is critical to suppress shuttle effects and promote conversion kinetics. [7] But lithiation of TMD materials inevitably gives rise to phase transformation and causes severe damage for the structural integrity of electrodes. [8] Silicon materials emerge as promising conversion-type substitute in recent years due to the high theoretical capacity of 4200 mAh g −1 , but silicon materials exit severe volume expansion effect in conversion processes, which will lead to rapid capacity degradation within several cycles. [9] These two typical conversion-type materials are both semiconductor materials with poor conductivity and unsatisfactory structural stability under electrochemical conditions. Construction of composition architectures with carbon materials is a common strategy to address these drawbacks for purpose of increasing conductivity and maintaining structural integrity. [10] Even if some synthetic methods have been deliberately considered and rationally designed, their attractive theoretical capacities have not fully expressed with long-term cycling performances. Thus, novel battery chemistries other than traditional insertion and conversion-type electrode materials need to be developed to address these issues.With the ever-increasing development of material science and engineering, lots of alternative materials with high energy capacities and stabilities have stood out as the electrode materials from the competition with conventional counterparts. For instance, sulfur material-based batteries gives high theoretical Advanced battery systems with high energy density have attracted enormous research enthusiasm with potential for portable electronics, electrical vehicles, and grid-scale systems. To enhance the performance of conversiontype batteries, various catalytic materials are developed, including metals and transition-metal dichalcogenides (TMDs). Metals are highly conductive with catalytic effects, but bulk structures with low surface area result in low atom utilization, and high chemical reactivity induces unfavorable dendrite effects. TMDs present chemical adsorption with active species and ...

Electrocatalysis is an efficient and promising means of energy conversion, with minimal environmental footprint. To enhance reaction rates, catalysts are required to minimize overpotential. Alternatives to noble metal electrocatalysts are essential to address these needs on a large scale. In this context, transition metal nitride (TMN) nanoparticles have attracted much attention owing to their high catalytic activity, distinctive electronic structures, and enhanced surface morphologies. Nickel‐based materials are an ideal choice for electrocatalysts given nickel's abundance and low cost in comparison to noble metals. In this Minireview, advancements made specifically in Ni‐based binary and ternary TMNs as electrocatalysts for the oxygen evolution reaction (OER) are critically evaluated. When used as OER electrocatalysts, Ni‐based nanomaterials with 3 D architectures on a suitable support (e.g., a foam support) speed up electron transfer as a result of well‐oriented crystal structures and also assist intermediate diffusion, during reaction, of evolved gases. 2 D Ni‐based nitride sheet materials synthesized without supports usually perform better than 3 D supported electrocatalysts. The focus of this Minireview is a systematic description of OER activity for state‐of‐the‐art Ni‐based nitrides as nanostructured electrocatalysts.
