Abstract

The research paper reports on a systematic study of structural and optical properties of ZnO nano rods for Photocatalytic Applications. Zinc oxide (ZnO) thin films were deposited on an ordinary glass substrate by dip coating technique and grown by hydrothermal method from aqueous solution of Zinc Nitrate and hexamethylenetetramine with seed layer of Zinc acetate dihydrate at low temperature of 100°C. The prepared ZnO nano rods were annealed at 500°C temperature in air atmosphere. Zinc acetate dihydrate and ethanol were used as a starting material and solvent respectively. The crystal structure and orientation of the ZnO nano rods were investigated by X-ray diffraction (XRD) patterns. The surface morphology of the ZnO thin films was investigated by Scanning Electron Microscopy (SEM). The optical absorbance and transmittance measurements were recorded by using a UV visible spectrophotometer and photoluminescence (PL) spectra. An optimized hydrothermally grown ZnO nano rods were prepared and investigated using sol-gel dip coating method for Photocatalytic Applications
