Preparation of Titania Nanorod Arrays by Hydrothermal Method

Article Preview

Abstract:

TiO2 nanorod arrays grown on FTO (fluorine-doped tin oxide) substrate were prepared in aqueuous solution of hydrochloric acid (HCl) and tetrabutyl titanate (C16H36O4Ti) using hydrothermal method. TiO2 nanorod arrays with different morphologies were obtained by systematically changing preparation conditions, including reaction temperature, reaction time, solution pH value, and concentrations of the reactants in the solution. Both morphology and crystalline structure of the samples were characterized. The prepared TiO2 nanorod arrays were used to assemble dye-sensitized solar cells, whose performances were also presented.
