چکیده

In this work, H3PW12O40 (PPT) and nano-sized titania supported on urea formaldehyde (UF) resin
was prepared via an impregnation method. The prepared sample was characterized by X-ray
diffraction (XRD), UV-Vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR),
scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The photo
catalytic activity of the PPT/TiO2/UF sample was evaluated by the decolorization of Bromothymol
Blue (BB), Direct Yellow12 (DY) and Texas Red (TR) dye solutions under UV-Vis and visible
light irradiation. The optical property of the PPT/TiO2/UF sample was evaluated by UV-Vis
spectrum. The effect of photocatalyst dosage and dye concentration on photo catalytic
decolorization of dyes was investigated. Photo catalytic efficiency of the PPT/TiO2/UF sample was
compared with TiO2/UF sample. Moreover, the reusability of the sample was examined.
