Fabrication of TiO₂ Spheres and a Visible Light Active α-Fe₂O₃/TiO₂-Rutile/TiO₂-Anatase Heterogeneous Photocatalyst from Natural Ilmenite.

ABSTRACT: High-purity (98.8%, TiO₂) rutile nanoparticles were successfully synthesized using ilmenite sand as the initial titanium source. This novel synthesis method was cost-effective and straightforward due to the absence of the traditional gravity, magnetic, electrostatic separation, ball milling, and smelting processes. Synthesized TiO₂ nanoparticles were 99% pure. Also, highly corrosive environmentally hazardous acid leachate generated during the leaching process of ilmenite sand was effectively converted into a highly efficient visible light active photocatalyst. The prepared photocatalyst system consists of anatase-TiO₂/rutile-TiO₂/Fe₂O₃ (TF-800), rutile-TiO₂/Fe₂TiO₅ (TFTO-800), and anatase-TiO
