单原子催化剂（SAC）因其卓越的催化性能而受到广泛关注。然而，高表面能限制了它们的合成，从而为进一步的开发带来了重大挑战。在过去的几年中，金属有机框架（MOF）由于其可定制的化学性质、可调节的形貌、高孔隙率和化学/热稳定性，作为合成 SAC 的理想候选者受到了广泛的关注。从这个角度来看，这篇综述彻底总结了之前报道的构建基于 MOF（MOF 衍生支持和 MOF 支持）SAC 的方法和未来可能的方法。然后，对基于 MOF 的 SAC 的识别技术进行了简要评估，以了解它们的配位环境、局部电子结构、空间分布和催化/电化学反应机制。本综述系统地重点介绍了基于MOF的SAC在能量转换和存储方面的几种光催化和电催化应用，包括析氢反应、析氧反应、O ₂ /CO ₂ /N ₂还原反应、燃料电池和可充电电池。通过强调基于 MOF 的 SAC 的优点和局限性，也为这个令人兴奋的领域的未来发展提供了一些线索。

Metal-organic framework-based single-atom electro-/photocatalysts: Synthesis, energy applications, and opportunities

Single-atom catalysts (SACs) have gained substantial attention because of their exceptional catalytic properties. However, the high surface energy limits their synthesis, thus creating significant challenges for further development. In the last few years, metal–organic frameworks (MOFs) have received significant consideration as ideal candidates for synthesizing SACs due to their tailorable chemistry, tunable morphologies, high porosity, and chemical/thermal stability. From this perspective, this review thoroughly summarizes the previously reported methods and possible future approaches for constructing MOF-based (MOF-derived-supported and MOF-supported) SACs. Then, MOF-based SAC's identification techniques are briefly assessed to understand their coordination environments, local electronic structures, spatial distributions, and catalytic/electrochemical reaction mechanisms. This review systematically highlights several photocatalytic and electrocatalytic applications of MOF-based SACs for energy conversion and storage, including hydrogen evolution reactions, oxygen evolution reactions, O₂/CO₂/N₂ reduction reactions, fuel cells, and rechargeable batteries. Some light is also shed on the future development of this highly exciting field by highlighting the advantages and limitations of MOF-based SACs.
