Ferrocene‐Functionalized Atomically Precise Metal Clusters Exhibit Synergistically Enhanced Performance for CO 2 Electroreduction

Abstract The integration of organometallic compounds with metal nanoparticles can, in principle, generate hybrid nanocatalysts endowed with augmented functionality, presenting substantial promise for catalytic applications. Herein, we synthesize an atomically precise metal cluster (Ag 9 Cu 6 ) catalyst integrated with alkynylferrocene molecules ( Ag 9 Cu 6 ‐Fc ). This hybrid catalyst design facilitates a continuous electron transfer channel via an ethynyl bridge and establishes a distinctive local chemical environment, resulting in remarkably enhanced catalytic activity in CO 2 electroreduction. The Ag 9 Cu 6 ‐Fc catalyst achieves a record‐high product selectivity of CO Faradaic efficiency of 100 % and an industrial‐level CO partial current density of −680 mA/cm 2 , surpassing the performance of the Ag 9 Cu 6 cluster (62 % and −230 mA/cm 2 , respectively) without ferrocene functionalizat…
