Enhanced Interface with Strong Charge Delocalization toward Ultralow Overpotential CO₂ Electroreduction.

ABSTRACT: The construction of an interface has been demonstrated as one of the most insightful strategies for designing efficient catalysts toward electrochemical CO₂ reduction (CO₂RR). However, the weak interfacial interaction and inherent instability inevitably hinder a further performance enhancement in CO₂RR attributable to the interface effect. Herein, 2 nm Ag nanoclusters (Ag NCs) are embedded onto CeO₂ nanospheres (CeO₂ NSs) with highly interconnected porosity (Ag NCs@CeO₂ NSs) to exclusively study the pure interface effect toward CO₂RR. The enhanced Ag-CeO₂ pure interface endows Ag NCs@CeO₂ NSs with a remarkably larger current density, significantly higher Faraday efficiency (FE), and energy ef
