Effective Toluene Ozonation over δ‑MnO2: Oxygen Vacancy-Induced Reactive Oxygen Species

To improve the reactivity and lifetime of catalysts in the catalytic ozonation of toluene, a simple strategy was provided to regulate the morphology and microstructure of δ-MnO2 via the hydrothermal reaction temperature. The effects of the reaction temperature and the ozone to toluene concentration...
