Supporting Data for "Study of Atomically Precise Metal Nanoclusters and Their Hybrids for Catalysis and Energy Storage"

Metal nanoclusters, particularly those composed of silver, copper, and gold, represent a fascinating class of materials due to their atomically precise structures. Unlike traditional metal nanoparticles, nanoclusters are characterized by well-defined formulas, such as [Mx(SR)y]q, which specify the exact number of metal atoms and ligands. Despite their appealing structures, there is limited research on the application of nanoclusters in catalysis and energy storage. Key findings of this thesis include the fabrication of doped Au-Ag nanoclusters integrated with the metal-organic framework ZIF-8, resulting in a significant enhancement of supercapacitor performance. Furthermore, the in-situ synthesis of bimetallic Au-Cu nanoclusters leads to a homogeneous dispersion on ZIF-8, yielding a specific capacitance that is 3.9 times higher than that obtained through ex-situ preparation methods. Additionally, this thesis details the effective synthesis of Au-Cu nanoclusters as a nanocatalyst, demonstrating their capability in facilitating three-component organic transformations. This work not only enhances our understanding of the structures and reactivity of nanoclusters but also underscores their potential applications in energy storage and catalysis.

金属纳米簇，尤其是由银、铜和金组成的纳米簇，由于其原子级精确的结构而构成了一类引人入胜的材料。与传统的金属纳米颗粒不同，纳米簇以明确的化学式，如[Mx(SR)y]q为特征，该化学式精确地指定了金属原子和配体的数量。尽管其结构颇具吸引力，但在催化和能量存储方面的纳米簇应用研究仍相对有限。本论文的关键发现包括掺杂Au-Ag纳米簇与金属有机框架ZIF-8的集成制造，从而显著提升了超级电容器的性能。此外，通过原位合成双金属Au-Cu纳米簇，实现了在ZIF-8上的均匀分散，其比电容是原位制备方法获得的3.9倍。此外，本论文详细阐述了Au-Cu纳米簇作为纳米催化剂的有效合成，展示了其在促进三组分有机转化方面的能力。这项工作不仅加深了我们对纳米簇结构和反应活性的理解，也强调了其在能量存储和催化领域的潜在应用。
