%X Nickel oxide-loaded activated carbon (NiO/AC) was prepared by the method of an incipient wetness impregnation at low temperature. The degradation of phenol by combined catalytic oxidation of NiO/AC and ozone under different pH and concentrations of t-BuOH was investigated. The crystal structure, surface morphology and textural properties of AC and NiO/AC were characterized by XRD, SEM and BET. The results showed that nickel was loaded on the surface of activated carbon in the form of rod-like nickel oxide. The surface area of NiO/AC decreased by 47.9% compared to that of AC. The reaction of O3/NiO/AC catalyzed ozonation of phenol followed the hydroxyl radical reaction mechanism. The removal efficiency of phenol was 29% higher than that of ozone.The removal rate of phenol has the positive correlation with the solution pH. It is confirmed that the catalytic performance of NiO/AC was stable, the maximum nickel ion concentration was 7 mg/L, which can be reused for several times.
