摘要：

The energy transition and electrification of the chemical industry necessitate electrocatalytic processes which have rapidly increased in interest over the past years. However, to have a sustainable impact on society and environment, industrial realization of the electrocatalytic processes is ultimately required. Since the stability parameter becomes more important in view of upscaling electrocatalytic processes, it is essential that researchers know about seemingly innocent procedures affecting the interpretation of faradaic efficiency and stability. We use the electrocatalytic reduction of CO2 to highlight important pitfalls and hidden ambiguities caused by improper experimental/mathematical procedures related to the calculation of faradaic efficiency, and critically discuss alternatives for a better assessment of electrocatalyst stability. The acquired insights are a first attempt to quantify and better evaluate electrocatalyst stability in order to improve comparability of experimental results and to optimize electrocatalysts or process conditions for durable performance.
