Abstract

•A novel TiO2&γ-Fe2O3@GO/PANI-NT nanotube is prepared as a green photocatalyst.•Its visible light photocatalytic activity is greatly higher than that of TiO2 nanoparticles.•The photocatalyst can be recovered easily and reused for the degradation of dye.•The activity enhanced mechanism is discussed in detail.

Synthesis of polyaniline-nanotubes (PANI-NT), in the presence of TiO2 and γ-Fe2O3 functionalized graphene oxide (GO), gives a green and magnetically recyclable photocatalyst, TiO2&γ-Fe2O3@GO/PANI-NT. The later orchestrates 94% photocatalytic efficiency in removal of rhodamine B (RB) from water, under simulated solar light irradiation. This is far higher than the 36% observed in the presence of TiO2&γ-Fe2O3@GO alone, where PANI-NT is excluded from the structure. Morphology, composition, and structural properties of our economically sound photocatalyst are characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy, thermo-gravimetric, transmission electron microscopy, inductively coupled plasma, RAMAN and Fourier-transform infrared spectroscopy.
