Visible Light Photodegradation of Diisopropanolamine Using Cu/TiO2 Photocatalyst: Effect of Metal Loading

Cu doped TiO2 at different metal loading was successfully prepared and investigated. Characterization of the prepared photocatalysts was carried out using X-ray diffraction (XRD), diffuse reflectance UVVis spectroscopy (DRUVVis) and scanning electron microscopy (SEM). Photodegradation study of aqueous diisopropanolamine solution (1000 ppm) using the prepared photocatalyst showed significant COD removal under visible light irradiation. The photocatalyst with 1.5 wt% Cu gave the highest COD removal of 45 %.
