The Preparation of Porous TiO2 Nanostructure by Triblock Copolymers Co-Templating Method of TiOSO4 Solution Derived from Ilmenite Ore
Porous titanium dioxide (TiO2) nanostructure has been successfully synthesized by a modified sol−gel 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 spherelike 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.
