Uncommon earth parts play an essential position in varied fields, which has attracted growing curiosity from the scientific neighborhood. In the meantime, single-atom catalysts present enormous benefits in lots of elements in contrast with conventional nanomaterials as a consequence of their 100% atomic utilization effectivity. Thus, the mix of the 2 ideas has yielded an environment friendly method to notice the high-value utilization of uncommon earth. On this mini-review, uncommon earth-based single-atom catalysts together with their synthesis strategies, characterization manners and corresponding functions are constructively summarized and mentioned. Particularly, the essential roles of uncommon earth parts as lively facilities in photograph/electrocatalytic reactions are targeted. Lastly, future prospects are additionally offered.
