copper oxide, nanoparticles, green synthesis, plant extract


Nanotechnology becomes the most innovative and interesting field for researchers in last decade. Nanotechnology deals with particles of size 1-100 nm. Recent advances in science and nanotechnology leads to the wide applications of metal and metal oxide nanoparticles in several fields. Copper oxide (CuO) nanoparticles have a large potential due to its distinct properties and environment friendly behaviour. There are several methods to synthesize CuO nanoparticles but due to environment benign process, availability of plants, non-toxicity and cheap process we prefer green approach. In this paper we synthesize CuO nanoparticles via green route in which Aloevera leaf (Aloe Barbadensis) extract used as reducing and capping agent. The formation of CuO can be found with naked eyes. The phytochemicals present in leaf extract plays an important role in synthesis. In synthesis process copper sulphate penta hydrate (Cu(So4)2.5H2O) use as metal precursor salt and NaOH used to maintain the pH of the solution. The synthesis process has been carried out at temperature 50 0C. The synthesized nanoparticles thereby obtained characterized by various analytical techniques like FESEM with EDX, XRD, FTIR and UV-Visible. The surface morphology of spherical shape revealed by Field Emission Scanning Electron Microscope (FESEM), elemental analysis by Energy Dispersive analysis (EDX), Fourier Transform Infrared (FTIR) revealed the different groups attached with CuO nps, the structure and average particle size of 5-6 nm estimated by XRD and the Optical properties revealed by UV-Vis spectroscopy.
