Surfactant Free Hydrothermal Synthesis of Copper Oxide Nanoparticles
2015
This paper describes a simple and versatile method for growing anisotropic plate shaped CuO nanostructures by simple, low temperature, and cost effective hydrothermal method. Scanning electron microscopy illustrated that the CuO nanostructures had an average particle size of 27nm. Structural analysis revealed that the CuO nanostructures had high crystal quality with the monoclinic crystal structure. Energy dispersive X-ray spectroscopy studies demonstrated that the sample was composed of CuO. The FTIR study also indicated the single-phase property and high crystallinity of as grown CuO nanostructures from its precursors. The optical band gap energy was very much larger than that of its reported values.
