  "abstract": "The oxidation activity of reducible oxides is closely linked to the nature of lattice oxygen species, and reductive treatments are often used to tailor the low-temperature reactivity by modifying the surface coordination environment. Here, using Co3O4 and the oxidation of 2-propanol as a model reaction, we demonstrate that a further enhancement of the low-temperature activity can be achieved by extending the reduction beyond conventional surface modification to access distinct, metastable CoO surface terminations. These terminations spontaneously reconstruct under oxidizing conditions into oxygen-rich surface structures that exhibit enhanced lattice oxygen reactivity and are key to the improved lowtemperature activity. This work establishes programmed surface reconstruction through a defined reduction-oxidation sequence as a strategy for engineering highly reactive lattice oxygen sites in reducible oxides.",
