Abstract Transition metal chalcogenides are an important class of electrocatalysts with broad application prospects in alkaline oxygen evolution reactions. Many researchers focusing on the situ conversion cations catalysts, but have rarely considered contribution oxidation, leaching, and re‐absorption to catalytic activity. Herein, multiple characterization approaches used monitor mechanism origin CoTe@CoS‐electrocatalyzed reaction (OER) The research results reveal that electro‐oxidative dissolution Te S electrode surface forms TeO 3 2− SO , which adsorbed surface. Moreover, species will further transform into 4 . As expected, extra addition mixed tellurite sulfate ions Co (OH) 2 electrolyte produces a synergistic effect can significantly boost OER Selenites analogous effect, indicating adsorption chalcogenates has universal improving performance. findings this work provide unique insights materials enhancing activity during processes.

The key to enhancing water electrolysis efficiency lies in selecting highly efficient catalysts. Currently, high-entropy alloys (HEAs) are utilized electrocatalysis applications owing their diverse elemental composition, disordered distribution, and the high solubility of each element, endowing them with excellent catalytic performance. experiments were conducted using isoatomic FeNiCrMo HEA as a precursor, high-activity three-dimensional nanoporous structure rapidly synthesized via electrochemical one-step dealloying choline chloride-thiourea (ChCl-TU) deep eutectic solvent (DES). results indicate that dealloyed Fe
