A novel anatase TiO 2 with nanostrawberry-like structure with high porosity has been synthesised on ITO, with the aid of microwave power in a very short duration of 6 minutes. The growth of these novel TiO 2 nanostructures on ITO is attained stoichiometrically by using ammonium hexafluoro titanate, Hexamethylenetetramine, and Boric acid as precursor, capping agent, and reducing agent, respectively . Optical absorption intensity and thickness of these nanostructure layers can be varied by the growth time. A highly porous, 2.25 µm thickest layer has been successfully synthesised on ITO, and the average diameter of these nanostructures was found approximately 70±2.5nm. These highly porous nanostructures are expected to be good candidate for photocatlysis applications and efficient photovoltaic performances of dye sensitised solar cells.
