TiO₂ /Cu was prepared by conventional impregnation method. PANI modified TiO₂ /Cu was prepared by chemical oxidative polymerization method. The synthesized composite was characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), Diffuse Reflectance Ultraviolet-Visible Spectroscopy (DRS-UV-Vis) and UV-Visible spectroscopy. It is found that composite exhibits excellent photocatalytic activity towards photodegradation of organic dye under visible light.
