Local compressive strain-induced anti-corrosion over isolated Ru-decorated Co₃O₄ for efficient acidic oxygen evolution.

ABSTRACT: Enhancing corrosion resistance is essential for developing efficient electrocatalysts for acidic oxygen evolution reaction (OER). Herein, we report the strategic manipulation of the local compressive strain to reinforce the anti-corrosion properties of the non-precious Co₃O₄ support. The incorporation of Ru single atoms, larger in atomic size than Co, into the Co₃O₄ lattice (Ru-Co₃O₄), triggers localized strain compression and lattice distortion on the Co-O lattice. A comprehensive exploration of the correlation between this specific local compressive strain and electrocatalytic performance is conducted through experimental and theoretical analyses. The presence of the localized strain in Ru-Co₃O₄ is co
