Modulating the dynamic change of catalysts is significant for understanding mechanism and exploiting better electrocatalysts but remains challenging in oxygen evolution reaction (OER). Herein, ceria-promoted reconstruction Ni-X (X = S, P, O) investigated to unravel correlation between reconstructed surface OER performance, which further guides design prominent electrocatalysts. Interfacial CeO2 promotes situ reconfiguration via strengthening hydroxyl adsorption, generating highly active CeO2-NiOOH interfaces. Moreover, rich vacancies formed after breaking Ni-S/P bonds leaching S/P anions render Ni3S2 Ni2P superior NiO with same modification, highlighting another dependence on pre-catalyst materials chemistry. Theoretical analysis confirms that co-presence interfaces can harmoniously regulate intermediate chemisorption toward favorable kinetics. As a proof concept, CeO2-modified exhibits low overpotentials 251 364 mV at current densities 10 100 mA cm–2 1.0 M KOH, respectively, performing among best recently reported Ni-based counterparts.

Abstract Active and stable electrocatalysts toward oxygen evolution reaction (OER) are essential for alkaline water splitting. Herein, an efficient durable high‐valence NiFe‐based OER electrocatalyst is developed, featuring a protective CeO 2− x coating to prevent the corrosion of carbon substrates during oxidative operation, ensuring excellent catalyst stability. The incorporation also leads formation Ce‐doped NiFe sulfide catalyst. Ce modulator enables dynamic transformation into highly active (oxy)hydroxide species with Ni sites enhanced Ni─O covalency, thereby improving its catalytic activity. Accordingly, prepared NiFeS 2 /CeO /CC achieves activity overpotential 260 mV at 100 mA cm −2 in 1.0 m KOH. Moreover, current density 187 hydrogen reaction. anion exchange membrane electrolyzer reached 500 1.73 V cell voltage stability h continuous operation. This study demonstrates promising approach fabrication robust water‐splitting electrocatalysts.
