A SIMPLE, FACILE APPROACH FOR THE LARGE SCALE SYNTHESIS OF CUO NANORODS, NANOFLOWERS AND NANOWIRES USING WET CHEMICAL ROUTE AND ITS GROWTH MECHANISM

Abstract

We report the large scale synthesis of nanostructured copper oxide (CuO) synthesized by cost effective and simple wet chemical route. Nanorods and Nanoflowers and Nanowires have been uniformly grown on Cu foil by the oxidation of Copper. Their growth mechanism has been reported to understand the optimal parameters for controlled growth via a simple coordination self-assembly method on substrates. The composition, morphology and structural identity have been characterized by Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Energy-Dispersive X-ray spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR) and Transmission Electron Microscope (TEM). These characterizations clearly show formation of CuO nanorods and nanoflowers having diameter in the range of 16-30 nm. The synthesized structures will have the potential applications as gas sensors, an active electrode material for Li-ion batteries, heterogeneous catalysts, field emission [FE] emitters and solar cells etc.
