Evaluation of the activity of electrocatalysts in the oxygen evolution reaction is important in the development of electrolyzers. However, at present there is no unified protocol for studying the electrochemical characteristics ofIridium iridium-containingIridium-containing catalysts in oxygen evolution reactionOER electrocatalysis (OER) in a three-electrodeElectrode cell, which complicates the comparison of the activity and stability of these materials between different research groups. In this work, we focused on studying the effect of activation stage conditions on the activity in OEROER electrocatalysis. We selected two activation modes that are often found in the literature: multiple cycling in the potential range of 0.0 - 1.5 V and chronoamprometric mode at E = 1.6 V. In our study, we found that the activation mode affects the change in the surface composition ofIridium iridium-containingIridium-containing catalysts, which in turn affects the values ​​of the kinetic parameters of the studied samples.
