Various electrolyte effects, including cation, anion, and pH effects, have been observed for many reactions. Notably, most models on L1 and L2 fall short in interpreting the electrolyte effects, as they often ignore the role of the electrolyte. Consensus is growing that these electrolyte effects originate from the change of the local reaction environment (LRE) at the catalyst-electrolyte interface, which is shaped by the interplay of macroscopic mass transport and microscopic EDL charging. Therefore, resolving the LRE and its influence on the multi-step kinetics has transpired as the focal point for further improvement, as emphasized in a recent Account of Xu et al., "The interplay of intrinsic microkinetics, homogeneous reactions, and mass transport limitations in determining the overall activity needs to be investigated in coupled transport-kinetic models."
