Metal nanoclusters have recently attracted considerable attention, not only because of their special size range but also because of their well-defined compositions and structures. However, subtly tailoring the compositions and structures of metal nanoclusters for potential applications remains challenging. Now, a two-phase anti-galvanic reduction (AGR) method is presented for precisely tailoring Au44 (TBBT)28 to produce Au47 Cd2 (TBBT)31 nanoclusters with a hard-sphere random close-packed structure, exhibiting Faradaic efficiencies of up to 96 % at -0.57 V for the electrocatalytic reduction of CO2 to CO.

硬球随机密排Au47 Cd2（TBBT）31纳米团簇，其法拉第效率高达96％，可将CO2电催化还原为CO。

金属纳米团簇最近吸引了相当大的关注，这不仅是由于其特殊的尺寸范围，而且还因为它们的定义明确的组成和结构。然而，为潜在应用巧妙地调整金属纳米团簇的组成和结构仍然具有挑战性。现在，提出了一种两相抗电化学还原（AGR）方法，用于精确定制Au44（TBBT）28以生产具有硬球体随机密排结构的Au47 Cd2（TBBT）31纳米团簇，其法拉第效率高达-0.57 V时96％用于电催化还原CO2为CO。
