Atomically precise noble metal (mainly silver and gold) nanoclusters are an emerging category of promising functional materials for future applications in energy, sensing, catalysis, and nanoelectronics. These nanoclusters are protected by ligands such as thiols, phosphines, and hydride and have sizes between those of atoms and plasmonic nanoparticles. In metallurgy, the properties of a pure metal are modified by the addition of other metals, which often offers augmented characteristics, making them more utilizable for real-life applications. In this Account, we discuss how the incorporation of various metal atoms into existing protected nanoclusters tunes their structure and properties.

金属团簇的原子级掺杂

原子精确的贵金属（主要是银和金）纳米团簇是新兴的有前途的功能材料，可用于未来在能源，传感，催化和纳米电子领域的应用。这些纳米团簇被诸如硫醇，膦和氢化物的配体保护，并且具有介于原子和等离子体纳米颗粒之间的尺寸。在冶金学中，纯金属的性能可以通过添加其他金属来改变，这些金属通常可以提供增强的特性，从而使其更可用于现实生活中。在本报告中，我们讨论了将各种金属原子掺入现有受保护的纳米团簇中如何调整其结构和性能。
