Synthesis of Novel Nano-Strawberry TiO2 Structures with the Aid of Microwave Inverter System: Growth Time Effect on Optical Absorption Intensity

Abstract

A novel anatase TiO 2 with nanostrawberry-like structure with high porosityhas 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 hexafluorotitanate, 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 m thickest layer has been successfully synthesised on ITO, andthe average diameter of these nanostructures was foundapproximately 70±2.5nm. These highly porous nanostructures are expected to begood candidate for photocatlysis applications and efficient photovoltaic performances of dye sensitised solar cells.
