Thiolate-protected metal nanoclusters, which are smaller than 2 nm and have a specific number of metal atoms, have been greatly investigated in areas such as catalysis, sensing, and energy conversion because of their unique chemical, optical, structural, and electronic properties. Doping monometallic nanoclusters with another metal offers the opportunity to enhance these properties even further. The atomic structure of thiolate-protected bimetallic nanoclusters has been thoroughly studied using various X-ray methods, but the electronic structures of these complexes are often under-discussed. This Perspective summarizes works examining the electronic properties (charge states and energy levels) of these materials using density functional theory, square-wave voltammetry, UV–vis spectroscopy, and X-ray photoelectron spectroscopy. This information is then related to the catalytic activities of these complexes in various representative reactions (e.g., carbon–carbon coupling, hydrogenation, and oxidation). The significance of the structure–property relationship between the electronic properties and the catalytic performance of thiolate-protected bimetallic nanoclusters is demonstrated.

硫醇盐保护的双金属纳米团簇：了解电子和催化性质之间的关系
硫醇盐保护的金属纳米簇小于2 nm，具有特定数量的金属原子，由于其独特的化学，光学，结构和电子特性，已在诸如催化，传感和能量转换等领域进行了大量研究。用另一种金属掺杂单金属纳米团簇可提供进一步增强这些性能的机会。硫醇盐保护的双金属纳米团簇的原子结构已使用各种X射线方法进行了深入研究，但这些配合物的电子结构常常未被充分讨论。该观点总结了使用密度泛函理论，方波伏安法，紫外可见光谱和X射线光电子能谱检查这些材料的电子性能（电荷态和能级）的工作。然后，这些信息与这些配合物在各种代表性反应（例如碳-碳偶联，氢化和氧化）中的催化活性有关。电子性质和硫醇盐保护的双金属纳米团簇的催化性能之间的结构-性质关系的重要性得到了证明。
