Cooperative Interfacial and Electrolyte Engineering in Au@Cu2O Core@Shell Nanocatalysts for Efficient CO2 Reduction to C2+ Products at Circumneutral pH

Small, EarlyView.
The e‐CO2RR performance of Au@Cu2O core–shell electrocatalysts is regulated by a cooperative interplay between shell thickness and electrolyte environments. In blank electrolyte, thin‐shelled variants leverage interfacial electronic synergy to optimize the copper oxidation state (OSCu) and maximize C2+ selectivity.
