| 제목 | Surface treated and metal oxide loaded rutile TiO2 nanorod photocatalyst for synergistic degradation of Orange (II) dye pollutant under solar light |
| 초록 | Transition metal oxides loaded acid treated TiO2 nanorods (NRs) were successfully prepared by chemical treatment and wet impregnation methods. The catalysts were characterized by XRD, TEM, XPS, FT-IR and UV-DRS. The photocatalytic activities of as-prepared, acid treated, metal oxide loaded and metal oxide loaded acid treated NRs were compared and dye degradation efficiency were determined from kinetics of the degradation of Orange (II) dye. Cobalt oxide 1w% loaded on 1.0 M acid treated TiO2 NRs exhibited the higher photocatalytic Orange (II) degradation efficiency 98.57% (within 120 min) than as-prepared and metal oxide loaded samples. The synergistic effect of cobalt oxide on acid treated TiO2 NRs over dye degradation is considered as fine dispersion of metal oxides on the OH rich surface of TiO2. The mechanism of enhanced photocatalytic activity and photoelectrochemical analysis of photocatalyst also studied. This work was supported by the BK21 plus program. |
