Abstract

In this study, Fe₂O₃/TiO₂ composites were successfully fabricated by a simple approach for treating titanium slag with dilute sulfuric acid, followed by a ball-milling process and calcination at a temperature of 400-800 ^oC in air. The resultant Fe₂O₃/TiO₂ composites were characterized by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), the N₂ adsorption-desorption isotherm, and UV–vis diffuse reflectance spectroscopy. The effects of the concentration of sulfuric acid and the calcinated temperature on the formation of the Fe₂O₃/TiO₂ composites were investigated in detail. The obtained Fe₂O₃/TiO₂ composite has a BET surface area, energy bandgap, and pH point of zero charge of 76.65 m²/g, 2,09 eV, and 8,45, respectively. Therefore, this as-prepared Fe₂O₃/TiO₂ composite could be a promising and cost-effective adsorbent for the effective removal of heavy metals and photodegradation of dyes from an aqueous environment.
