The ZnO nanorods have been successfully synthesized by seed layer preparation using dip coating method and by growth layer preparation using hydrothermal method. The prepared ZnO nanorods were characterized using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and UV-Visible spectrophotometer (UV-Abs).. These ZnO nanostructures were explored as catalyst for solar-light induced photo catalytic degradation of methylene blue dye in an aqueous solution. The degradation rates depend on the dye structure, concentration, solvent-dependent ZnO film morphologies, pH of the medium and excitation light source. The photocatalytic performances of the obtained ZnO nanorods were deeply investigated for possible application of textile/water treatment.
