There are obstacles with using conventional nanoparticle catalysts for developing atomic-by-atom tailoring of active sites in the heterogeneous catalysis field. However, atomically precise metal clusters with precise formulas and crystallographically determined structures, which may build a bridge between single atoms and nanoparticles, may become possible to unravel the respective contributions of every atom in a cluster to its overall catalytic performances and build the structure–property relationship at an atomic-precision level. In this Review, we will first describe recent advances of CO₂ electronic reduction catalyzed by Au-based clusters including pure gold and its alloys. We will then put a particular emphasis on chemical fixation of CO₂ into organic molecules, such as alkyne, epoxide, and amine, over gold cluster catalysts. Additionally, we will concisely introduce the discovery of catalytic selectivity of the Au-based clusters in CO₂ hydrogenation toward C₁ and C₂ products. Finally, we will provide our perspectives on some issues for catalytic conversion of CO₂ over atomically precise metal clusters in future catalysis research.

原子级精确金基簇催化剂上的 CO2 催化转化

使用传统的纳米颗粒催化剂在多相催化领域开发活性位点的逐个原子定制存在障碍。然而，具有精确分子式和晶体学确定结构的原子级精确金属簇可能会在单个原子和纳米粒子之间架起一座桥梁，可能会揭示簇中每个原子对其整体催化性能的各自贡献并构建结构-性能原子精度级别的关系。在这篇综述中，我们将首先描述由金基团簇（包括纯金及其合金）催化的 CO ₂电子还原的最新进展。然后我们将特别强调CO _{2的化学固定}在金簇催化剂上转化为有机分子，如炔烃、环氧化物和胺。_{此外，我们将简要介绍在 CO 2}加氢中 Au 基团簇对 C ₁和 C ₂产物的催化选择性的发现。最后，我们将就未来催化研究中原子级精确金属簇上CO ₂催化转化的一些问题提供我们的观点。
