| Summary: | TiO 2 nanoparticles with various morphologies have been synthesized under various temperature conditions, namely 25, 50, 60 and 90�C via a liquid phase deposition technique. The liquid phase deposition technique is an electroless deposition of TiO 2 onto the substrate surface via a unique hydrolysis of titanium complexes in the presence of H 3 BO 3 . FESEM characterization on the samples showed that, under the temperature treatment, the nanostructures morphology transformed from grass-like to agglomerated spherical-like shape with the increased of the temperature. The XRD analysis performed on these samples show that all of the samples were anatase and unmodified with the change in the morphology. The optical absorption window of the TiO 2 nanostructures films was also found to enlarge with the increasing of the growth temperature, resulting from the structure modification. Owing to its simplicity, the present technique may produce TiO 2 nanoparticles with a variety of morphologies for use in photocatalyst and solar cell applications. � 2012 Elsevier B.V. |
