Porous metal oxides are of high demand for catalytic and photocatalytic applications. Recently several research groups have reported on the synthesis of TiO2and ZnO2 porous structures using ultrasonic hydrolysis of the precursors,[1] tri-block copolymers,[2] or using porous silica as hard template.[3] However, reports on the synthesis of porous TiO2 structures with ordered and size controlled pores are rare. Here we report on the synthesis of mesoporous TiO2structures with ordered pores using Pluronic F-68 triblock co-polymer as soft template. The porous TiO2 powders were prepared by simple EISA method using titanium (IV) butoxide as precursor. The pore size and their order have could be varied by varying the polymer concentration. The porous materials were analyzed by transmission electron microscopy (TEM), X-ray diffraction and nitrogen adsorption-desorption isotherms.
