High-efficiency electrocatalysts with superior activity and stability are crucial to practical applications in water splitting, including the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). Downsizing the conventional nanoparticle catalyst to single atoms and constructing single-atom catalysts (SACs) is a rapidly emerging research focus. Because of the involvement of unique single-atom active moieties and the strong metal–support interactions arising from interfacial bonding, SACs as promising alternatives to noble metal-based nanoparticle catalysts exhibit profound power in the HER and OER. Here, we present a perspective on the exciting advances of SACs for HER and OER applications, with an emphasis on innovative synthetic strategies and an in-depth understanding of the structure–activity relationship through a combination of systematic characterization and theoretical studies. Finally, the challenges and some of the critical issues in this field are addressed.

用于电化学水分解的单原子催化剂

具有卓越活性和稳定性的高效电催化剂对于水分解中的实际应用至关重要，包括氢析出反应（HER）和氧析出反应（OER）。将常规纳米颗粒催化剂小型化为单原子并构建单原子催化剂（SAC）是快速兴起的研究重点。由于独特的单原子活性部分的参与以及界面键合产生的强大的金属-载体相互作用，SAC作为贵金属基纳米粒子催化剂的有前途的替代品在HER和OER中显示出强大的功能。在这里，我们将介绍用于HER和OER应用的SAC令人兴奋的进展，着重于创新的合成策略，并通过系统表征和理论研究相结合来深入理解结构与活性之间的关系。最后，解决了该领域中的挑战和一些关键问题。
