This study uses a multimodal approach to investigate how Co2MnO4 and CoMn2O4 electrocatalyst surfaces dynamically reconstruct and transform during the oxygen evolution reaction (OER). The findings reveal that Co2MnO4 forms Co-Mn oxyhydroxides with an optimal Co/Mn ratio, which enhances OER stability through Mn dissolution and redeposition, while CoMn2O4 forms less active Mn-rich oxides during the process.
