Mechanistic Insights Into Zn‐Promoted CO 2 Electroreduction on α‐CuZn Alloys in Aprotic Media

Year: 2026

Type: article

Abstract: How Zn enhances the performance of Cu electrocatalysts for RR in nonaqueous electrolytes remains an open question. Herein, we address this question by combining electrochemical measurements, kinetic modeling, and DFT calculations to elucidate Zn's role in boosting the electrocatalytic activity of Cu. Cyclic and linear sweep voltammetry reveal enhanced reduction activity with increasing Zn content, up to threefold higher current density at 25 wt.% Zn. Kinetic modeling attributes this to improved activation, while DFT confirms that Zn sites energetically stabilize Cu‐adsorbed . This work uncovers the mechanism behind CuZn alloys’ superior performance, guiding design of efficient RR catalysts for sustainable energy conversion.
