TiO2 is one of the most effective metal oxide materials due to its high photocatalytic efficiency, photochemical stability, non-toxic nature, and low cost. Especially the fabrication of mesoporous TiO2 nanoparticles has attracted considerable interest because of their large surface area which is key parameter in enhancing the effectiveness of TiO2 in various applications. In this work, mesoporous titania nanoparticles were prepared by using PS-b-PEO and Pluronic F127 as structure-directing agents and titanium tetraisopropoxide as titanuim precursor. The mesoporous titania nanoparticles were fabricated by drop-casting method from mixture solution containing polymer solution and the precursor via sol-gel reaction. Calcination process was conducted to remove organic materials and to crystallize at high temperature. The characteristics of mesoporous titania nanoparticles were examined by AFM and FE-SEM. |
