Single-atom catalysts (SACs) hold great promise for maximized metal utilization, exceptional tunability of the catalytic site, and selectivity. Moreover, they can substantially contribute to lower the cost and abundancy challenges associated with raw materials. Significant breakthroughs have been achieved over the past decade, for instance, in terms of synthesis methods for SACs, their catalytic activity, and the mechanistic understanding of their functionality. Still, great challenges lie ahead in order to render them viable for application in important fields such as electrochemical energy conversion of renewable electrical energy. We have identified three particular development fields for advanced SACs that we consider crucial, namely, the scale-up of the synthesis, the understanding of their performance in real devices such as fuel cells and electrolyzers, and the understanding and mitigation of their degradation. In this Perspective, we review recent activities of the community and provide our outlook with respect to the aspects required to bring SACs toward application.

单原子催化剂：电化学能量转换应用展望

单原子催化剂 (SAC) 有望最大限度地提高金属利用率、催化位点的出色可调性和选择性。此外，它们可以大大有助于降低与原材料相关的成本和丰富的挑战。在过去十年中取得了重大突破，例如，在 SAC 的合成方法、催化活性和对其功能的机理理解方面。尽管如此，为了使它们在重要领域（例如可再生电能的电化学能量转换）中的应用可行，还面临着巨大的挑战。我们已经确定了我们认为至关重要的先进 SAC 的三个特定开发领域，即合成的放大、了解它们在燃料电池和电解槽等真实设备中的性能，以及了解和减轻它们的退化。在这个视角中，我们回顾了社区最近的活动，并就将 SAC 引入应用程序所需的方面提供了我们的展望。
