Abstract
Nanotechnology has become most outweigh to present generation and commercial in the modern world owing to its compact size, surface, volume and shape of the nanoparticles in every field. Copper oxide (CuO) nanorods are synthesized using the precursor copper sulfate pentahydrate (CuSO4.5H2O) and reactive agent sodium hydroxide (NaOH), via simple hydrothermal method followed by annealation. The synthesized CuO nanorods are subjected to various optical and structural characterizations, UV-Visible spectra confirmed the presence of copper oxide by showing the maximum absorption intense peak (λmax). From the graph (αhv)2 Vs hv we calculated the energy band gap of CuO nanorods Using Kubelka-Munk transformation equation from the obtained UV-Visible absorption data. The compositional assignment is analysed using the FTIR spectroscopy. Structure of the CuO, mass and atomic percentage are confirmed by the SEM-EDS. Phase and size of the CuO nanorods are confirmed by XRD spectra. Copper oxide nanorods have good outweigh in Photocatalytic, conducting, storage purpose owing of nanorod structure. Copper oxide nanorods are shows the effective dye degradation when it is illuminated to UV light with respect to time.
