Abstract

A novel GO/Fe₃O₄/PANI ternary photocatalyst was prepared using facile mechanochemical mixing. The composite nature of the material was confirmed due to the existence of distinct diffractions and absorption bands of the components of GO/Fe₃O₄/PANI in XRD, FT-IR and absorption spectra, respectively. Band gap evaluation revealed a blue shift in the band gap energy (∼3.02 eV) of PANI in composite with the mixing of GO and Fe₃O₄. A porous amorphous surface wherein Fe₃O₄ nanoparticles embedded on a GO sponge wrapped by a polyaniline network was noticed in scanning electron micrographs. Photocatalytic studies showed that 10 mg of GO/Fe₃O₄/PANI removed over 92 % of 10 ppm rhodamine B (RhB) dye in 60 min. of natural sunlight illumination (700 × 10² ± 100 lx). Moreover, kinetic studies revealed that the removal of RhB followed the pseudo-first-order kinetic model.
