The catalytic volatile organic compound oxidation poses a dilemma for perovskite (ABO) catalysts, as their high lattice oxygen reactivity (electron-deficient O) depends on attracting coordinated oxygen electrons through an increased electronegativity of B-site cations, but this impedes the healing of oxygen vacancies and thus results in a low concentration of active lattice oxygen due to the limited O dissociation in electron-deficient environments. Herein, we compress [Co/MnO] octahedra through A-site Cs doping in the double perovskite (LaCoMnO), which optimizes the orbital hybridization between Co/Mn 3d and O 2p. This promotes electron transfer from O to Co/Mn while reducing Co/Mn electronegativity, resulting in a synergistic improvement of lattice oxygen reactivity and oxygen vacancy healing.
