While largely overlooked, there have been some experimental reports recognizing the role of the "desorption-re-adsorption-reaction" mechanism in individual cases. In their original work, Behm et al. purposefully manipulated the catalyst loading to demonstrate how selectivity depends upon surface roughness during the eORR on Pt 17 as well as the electrochemical oxidations of methanol (eMeOHox) and ethanol (eEtOHox). More recently, similar mechanistic arguments were made to explain the varying selectivity towards CO during the eCO 2 RR on Cu when changing the catalyst morphology (via e.g. nanoparticle coverage, distance, shape, and size) or the reactant stream in reactor setups. And yet, the impact of the "desorption-re-adsorption-reaction" mechanism as well as its generalization across different processes and systems remain unclear.
