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.
