ABSTRACT

In this study, a nanocomposite consisting of iron-doped titanium dioxide (FeTiO2) and spinel NiFe2O4 were employed to enhance dye removal using the advanced oxidative process H2O2/UV. The co-precipitation method was used to synthesize both FeTiO2 and spinel, followed by characterization using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. To evaluate their efficiency as photocatalysts, the materials were tested under UV light irradiation for the degradation of Rhodamine B in water. Kinetic studies revealed that the reaction followed pseudo-first-order kinetics, with a rate constant of 6.95×10–3 min–1 and degradation efficiencies of 68.57%, 67.21%, and 74.18% for NiFe2O4, FeTiO2-Im, and FeTiO2-SG, respectively. FeTiO2-SG exhibited superior photocatalytic performance compared to spinel for the degradation of Rhodamine B, suggesting that FeTiO2 is an efficient photocatalyst for the decolorization of Rhodamine B.
