Heterogeneous Catalytic Ozonation of Acid blue 62 Over Nanorod Fe-OMS-2
In this work, nanorod materials prepared by refluxed method (K-OMS-2) and by co-precipitation method (Fe-OMS-2) were analyzed by X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM). Non-catalytic and heterogeneous catalytic ozonation processes of acid blue 62 (AB-62) w...

description | In this work, nanorod materials prepared by refluxed method (K-OMS-2) and by co-precipitation method (Fe-OMS-2) were analyzed by X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM). Non-catalytic and heterogeneous catalytic ozonation processes of acid blue 62 (AB-62) were tested under the bubbling O3/air flow, at room temperature (RT). Comparing to ozonation over Fe-OMS-2, both adsorption and non-catalytic ozonation of AB-62 showed much lower removal efficiency. These results evidenced a positive role of nanorod Fe-OMS-2 in removal of (80% of AB-62 after 50 min of O3 bubbling. The pseudo first-order reaction with respect to the AB-62 was observed from ozonation over K-OMS-2 and Fe-OMS-2 catalysts. The reaction rate measured from Fe-OMS-2 is three times faster than that from K-OMS-2 probably contributed from a synergistic effect between O3 and defects on the surface of Fe-OMS-2. |
