Abstract Rare earth (RE)‐based perovskites are considered as promising platform for oxygen evolution reaction (OER) due to their low cost and tunable structures. However, the systematic synthesis of perovskite catalysts with satisfactory performance has rarely been reported. Herein, a general synthetic protocol RE‐substituted LaCoO 3 (RE‐LCO) is demonstrated. Particularly, after loaded RuO 2 , as‐prepared :0.2Ce‐LCO hybrid structures exhibit OER overpotential 135 mV at 10 mA cm −2 in 1.0 m KOH, together remarkable long‐term operation, representing one most efficient robust Ru‐based catalysts. Comprehensive experimental results indicate that enhanced mechanism attributed Ce‐substitution, which alters geometric configuration CoO 6 octahedra generates more vacancies. Furthermore, interaction between Ce‐LCO stabilizes valence state Ru site. Theoretical calculations corroborate Co 3d orbitals overlap Ce 4f near Fermi level, greatly improving electron transfer atoms.
