Abstract

In this paper, a new series of Fe2TiO5 - polypyrrole (FTO-xP) were prepared by the facile polymerisation method using sulphuric acid and hydrogen peroxide as oxidising agents. The synthesised compounds were characterised by diffuse reflectance spectroscopy (DR/UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), microscopic analysis (SEM) and specific surface area analysis (BET) to evaluate their optical and surface properties, morphology, phase composition and crystallinity. The new composites were used for photocatalytic removal of micropollutants: highly toxic Cr(VI) and (IBU). The effect of polypyrrole content in the composite on the efficiency of selected micropollutants degradation was investigated. The results showed that FTO-xP composites had better adsorption capacity and photocatalytic activity than single components. Hybrid FTO-xP composites could efficiently remove inorganic/organic micropollutants in the aqueous phase.
