Redox-Engineered Co─Cu─Zr Perovskites for Durable Anion Exchange Membrane Electrolysis.

ABSTRACT: The oxygen evolution reaction (OER) remains a critical bottleneck in water electrolysis and air-battery systems, requiring electrocatalysts with both high activity and long-term stability. Herein, Ba(Zr_xCu_yCo_1-x-y)O_3-δ (BZCC), a novel mixed-metal perovskite synthesized is introduced via a low-temperature hydrothermal method, which integrates multiple catalytic functionalities for efficient OER in alkaline media. The catalyst simultaneously activates the adsorbate evolution mechanism (AEM) and the lattice oxygen oxidation mechanism (LOM), driven by the redox flexibility of Co³⁺/Co⁴⁺. The incorporation of Cu²⁺/Cu³⁺ modulates the electronic structure to enhance intrinsic activity, while Zr⁴⁺ con
