摘要：
The photocatalysts of Cs doped bare TiO2, 0.50 and 1.0 wt% were prepared by wet-impregnation method and characterized by XRD, SEM-EDX, TEM, BET, ICP, FTIR, and UV-DRS analyses. The degradation of bromoxynil was investigated under visible irradiation with ozone to compare the efficiency of these photoinduced advanced oxidation techniques. Photocatalysis with 1% Cs/TiO2 was yielded 100% degradation and mineralization of bromoxynil in 2 h at basic pH. The extent of degradation was confirmed by GC-MS. The oxidation products were identified by H-1 NMR and GC-MS spectral analyses. The catalyst is fully recoverable and reusable multiple times with no loss of activity.
