Synthesis of Nanostructure TiO2 Nanorod Array on FTO Substrate using Hydrothermal Method and its Photocatalytic Activity

In this work, one dimensional TiO2 nanorods array (NRA) was prepared by using hydrothermal method.The TiO2 NRA was grown on FTO substrate without using seed layer substrate.The effect of hydrothermal temperature and time on the morphology of TiO2 NRA was studied.The synthesized TiO2 nanostructure was characterized by different techniques.The structural properties were studied using X-Ray diffraction (XRD) technique, The morphological studied was done with Field emission scanning electron microscope (FE-SEM), UV-Visible spectroscopy and photoluminescence (PL) were used to evaluate optical properties of synthesized TiO2 nanostructures.The results showed that synthesized TiO2 nanorod array were grown vertically on FTO substrate with average diameter 50 nm and length up to 1 µm was achieved at about 1 µm.The photodegradation performance of TiO2 NRA was also studied and it was achieved up to 47% in 180 min under UV irradiation.
