Rare earth elements play an important role in various fields, which has attracted increasing interest from the scientific community. Meanwhile, single-atom catalysts show huge advantages in many aspects compared with traditional nanomaterials due to their 100% atomic utilization efficiency. Thus, the combination of the two concepts has yielded an efficient way to realize the high-value utilization of rare earth elements. In this mini-review, rare earth-based single-atom catalysts including their synthesis methods, characterization means and corresponding applications are constructively summarized and discussed. In particular, the important roles of rare earth elements as active centers in photo/electrocatalytic reactions are focused on. Finally, future prospects are also provided.
稀土元素在各个领域发挥着重要作用，这引起了科学界越来越多的关注。同时，单原子催化剂由于其100%的原子利用效率，在许多方面与传统纳米材料相比具有巨大优势。因此，这两个概念的结合产生了一种实现稀土元素高值利用的有效方法。在这篇综述中，对基于稀土的单原子催化剂，包括其合成方法、表征手段及相应应用进行了建设性的总结和讨论。特别关注了稀土元素作为光/电催化反应活性中心的重要作用。最后，还展望了未来前景。
