Cu–Zn bimetallic catalysts were synthesized on 3-D gas diffusion electrodes using atomic layer deposition (ALD) techniques. Electrochemical CO₂ reduction was evaluated, and a significant variation in the product selectivity was observed compared to unmodified Cu catalysts. As low as a single ALD cycle of ZnO resulted in a reduction of C₂H₄ production and shift towards CO selectivity, which is attributed to changes in the chemical state of the surface. Our findings demonstrate the impact of atomically-precise surface modifications on electrocatalyst selectivity.

使用原子层沉积调整双金属 Cu 电催化剂对 CO2 还原的选择性


使用原子层沉积 （ALD） 技术在 3-D 气体扩散电极上合成了 Cu-Zn 双金属催化剂。评估了电化学 CO₂ 还原，与未改性的 Cu 催化剂相比，观察到产品选择性存在显著变化。低至 ZnO 的单个 ALD 循环导致 C₂H₄ 产生减少，并转向 CO 选择性，这归因于表面化学状态的变化。我们的研究结果证明了原子精确的表面修饰对电催化剂选择性的影响。
