Understanding the fundamentals behind an electrocatalyst's selectivity enables the ability to steer product formation. Herein, we study Cu nanowires doped with a small amount of Al (12%) for COR, which enhances formate production by 16.9% over pure Cu nanowires. Density functional theory calculations and COR were employed to posit the preference of the formate formation pathway as a result of the Al doping.
了解电催化剂选择性背后的基本原理可以使我们能够控制产物的形成。在此，我们研究了掺杂少量铝（12%）的铜纳米线在 CO 还原反应（COR）中的性能，结果表明掺杂铝的铜纳米线相对于纯铜纳米线可将甲酸盐的生成率提高 16.9%。通过密度泛函理论计算和 COR，我们提出了由于铝掺杂导致甲酸盐形成途径偏好的观点。
