Identifying the dynamic evolution of catalysts is crucial to revealing its structure-performance relationships. In this issue of Chem Catalysis, Kang and co-workers study Rh-MoS₂ evolution during the hydrogen evolution reaction and show that it converts from Rh-S to Rh-S/O and from 1T-MoS₂ to 2H-MoS₂, resulting in a balance between activity and stability.

单原子Rh位点的动态演化和MoS2对析氢的支持

识别催化剂的动态演化对于揭示其结构与性能的关系至关重要。在本期《化学催化》中，Kang 及其同事研究了析氢反应过程中 Rh-MoS ₂ 的演化，并表明它从 Rh-S 转化为 Rh-S/O，并从 1T-MoS < b1> 到 2H-MoS ₂ ，从而达到活性和稳定性之间的平衡。
