Metal nanoclusters (MNCs) are compositionally well-defined and also structurally precise materials with unique molecule-like properties and discrete electronic energy levels. Atomically precise ligand-protected Cu nanoclusters (LP-CuNCs) are one category of typical MNCs that usually demonstrate unique geometric and electronic structures to serve as electrocatalysts. However, the synthesis, application, as well as structure-performance relationship of LP-CuNCs are not adequately studied. Significantly, the ligands are essential to the geometric structure, crystal structure, size, and electronic structure of LP-CuNCs, which determine their physiochemical properties and applications. In this review, significant progress in the ligand design of LP-CuNCs, and their application in electrocatalytic reactions is introduced. The general basics of ligand-protected MNCs (LP-MNCs) are first introduced and the functions of ligands are emphasized. Subsequently, a series of different ligands for LP-CuNCs including thiolates, phosphines, alkynyl, polymers, and biomolecules are highlighted. Thereafter, their applications in different electrocatalytic reactions are discussed. It is believed that this review will not only inspire the design and synthesis of novel LP-CuNCs, but also contribute to the extension of their applications in electrocatalytic reactions and the establishment of accurate structure-performance relationships.

原子级精确的铜纳米团簇的配体设计及其在电催化反应中的应用

金属纳米团簇（MNC）是成分明确、结构精确的材料，具有独特的类分子特性和离散的电子能级。原子精确的配体保护的铜纳米簇（LP-CuNC）是一类典型的跨国公司，通常表现出独特的几何和电子结构，可用作电催化剂。然而，LP-CuNCs的合成、应用以及结构与性能的关系尚未得到充分研究。值得注意的是，配体对于 LP-CuNC 的几何结构、晶体结构、尺寸和电子结构至关重要，这决定了它们的理化性质和应用。在这篇综述中，介绍了 LP-CuNC 配体设计的重大进展及其在电催化反应中的应用。首先介绍了配体保护的跨国公司（LP-MNC）的一般基础知识，并强调了配体的功能。随后，重点介绍了一系列不同的 LP-CuNC 配体，包括硫醇盐、膦、炔基、聚合物和生物分子。此后，讨论了它们在不同电催化反应中的应用。相信本次综述不仅将启发新型LP-CuNCs的设计和合成，而且有助于扩展其在电催化反应中的应用以及建立准确的结构-性能关系。
