Photocatalytic decolorization of methyl green using Fe(II)-o-phenanthroline as supported onto zeolite Y

The potential of Fe(II)-orthophenantroline photocatalyst, doped on zeolite Na-Y via complexation process, was studied in decolorization of methyl green. The characterization of samples was studied using XRD, FT-IR, TG/DTG and SEM methods. The best photodecolorization efficiency was obtained at: 1 g L−1 catalyst, 40 ppm MG, pH: 9 using catalyst containing 7 mg per gram catalyst. The degradation process obeyed first-order kinetics. The reusability of the intended catalyst was also investigated. Homogeneous photodecolorization using unsupported complex does not significant role in photodecolorization of the dye, which confirms the importance of zeolitic support to prevent the aggregation of complex particles.
