The Preparation of Porous TiO₂ Nanostructure by Triblock Copolymers Co-Templating Method of TiOSO₄ Solution Derived from Ilmenite Ore

Abstract:

Porous titanium dioxide (TiO₂) nanostructure has been successfully synthesized by a modified solgel method using non-ionic triblock copolymer pluronic F-127 as surfactant template and titanylsulfate (TiOSO₄) solution as the inorganic precursor derived from the sulfuric process of Bangka-Indonesia ilmenite ore. The resulting nanostructure samples were characterized by XRD, SEM, TEM and UV-Vis spectroscopy. The results showed that porous titania particles have sphere-like shape and can be indexed as the anatase phase with average crystallite size of about 5-7 nm, narrow pore size distribution with an averange pore diameter of about 3-5 nm and band gap energy in the range of 3.10 3.16 eV.
