Synthesis of ZnO nanorods by novel surfactant assisted wet chemical method and its Photocatalytic Activity
Keywords:
Nanorods, Congo Red, Photocatalytic activity, Tauc plot, Band gapAbstract
In this paper, synthesis of ZnO nanorods is done by a simple and surfactant assisted wet chemical method. The obtained ZnO nanorods can be characterized using various techniques like Powder X-ray Diffraction (PXRD), Field Emission Scanning Electron Microscopy (FESEM) and UV-DRS Spectroscopy. XRD results reveal that the sample is crystalline with a hexagonal wurtzite phase with the particle sizes of 30 nm. Field Emission Scanning Electron Microscopy (FESEM) result reveals that the ZnO nanoparticles are rod like shaped. The band gap of ZnO nanorods were determined from Tauc Plot. The photocatalytic activity of ZnO nanorods has been examined by the degradation of Congo Red dye using UV light.
