Pulsed electrolysis has emerged as a promising approach to CO reduction, offering a simple method to adjust product selectivity and enhance operational stability. However, conceptually applying the dynamic pulse operation process on a large scale highlights its differences when compared to conventional electrolysis processes, impacting the economic feasibility of the process. We discuss the influence of pulsed electrolysis on surface reaction mechanisms and the simulation of changes at both the continuum and smaller scales through computational modeling. Additionally, we point out considerations for applying pulsed CO electrolysis to a large-scale process and assess their economic implications, comparing pulsed electrolysis with constant electrolysis.
脉冲电解已成为一种有前景的二氧化碳还原方法，提供了一种调节产物选择性和提高操作稳定性的简单方法。然而，从概念上将动态脉冲操作过程大规模应用时，与传统电解过程相比凸显了其差异，影响了该过程的经济可行性。我们通过计算建模讨论了脉冲电解对表面反应机制的影响以及在连续尺度和较小尺度上变化的模拟。此外，我们指出了将脉冲二氧化碳电解应用于大规模过程的注意事项，并评估其经济影响，将脉冲电解与恒电流电解进行比较。
