| Özet |
| A group of novel azo-bridged phenolic iron(II) phtalocyanine (Fe(II)Pcs) derivatives which have peripheral or non-peripheral substitution on macrocyclic ring were produced and characterized employing various spectroscopic methods. Peripheral or nonperipheral substituted Fe(II)Pc molecules (defined as Fe(II)Pc-1, Fe(II)Pc-2, Fe(II)Pc-3, Fe(II)Pc-4) were used for sensitization of TiO2 nanopowder to prepare photoactive composite catalysts (Fe(II)Pc/TiO2, 1% of the mass of TiO2) using wet deposition method. The as-obtained composite materials were characterized by SEM, EDX, UV-Vis DRS and XRD. The results revealed that the Fe(II)Pc derivatives were successfully immobilized on TiO2 and the anatase crystalline phase have absorption in the visible light region. Fe(II)Pc sensitized catalysts were tested for the photocatalytic removal of 4-chlorophenol (4-CP) in the presence of H2O2. Photocatalytic experiments showed that the H2O2 assisted Fe(II)Pc/TiO2 composites achieved high degradation of 4-chlorophenol except for Fe(II)Pc-4/TiO2. The photocatalytic efficiencies of the catalysts follow the order: Fe(II)Pc-3/TiO2 (93.21%) > Fe(II)Pc-1/TiO2 (87.61%) > Fe(II)Pc-2/TiO2 (83.86%) > TiO2 (67.74%) > Fe(II)Pc-4/TiO2 (64.71%). |
