X-Ray Diffraction pattern, as shown in Figure 1, confirmed the successful synthesis of copper nanoparticles with a shell of copper oxide; wherein the main diffraction peaks characterize the elemental copper were detected at 2θ = 43.2745, 50.4083 and 74.1706° which correspond to the (1 1 1), (2 0 0), and (2 2 0) crystal faces of copper Copper, as a red-brown metal, is in high demand with a usage of more than 20 million tons per year.
It was found that nanoscaled CuO, generated by thermal plasma technology, contains traces of pure Cu and Cu 2 O nanoparticles. Copper nanoparticles act as antimicrobial agent in various fields.
Copper Nanoparticles in the size range 50-100nm were synthesized successfully by using green strategy .Optical band Gap as obtained from the UV analysis increases as the size of the Copper Nanoparticles increases which in turn depends upon the concentration of copper ions taken in the solution. Copper(II)-oxide nanoparticles can be synthesized through different ways, the sizes and shapes of desired nanostructures materials can be controlled by limited number of synthetic factors such as: method, solvents, surfactants, starting precursors temperature…. This paper reports a simple, direct and in situ route to prepare different graphene/copper oxide nanoparticles thin films, followed by the demonstration of their use as precursors for graphene/copper hexacyanoferrate. Many nanoparticles (NPs) are transformed in the environment, and the properties of the transformed materials must be determined to accurately assess their environmental risk. The copper is highly toxic to microorganism such as bacteria (E-Coli, Staphylococcus Aureus, Pseudomonas aeruginosa)and non-toxic to animal cells, due to these phenomena it is considered to be an effective bactericidal metal. Synthesis and optical characterization of copper oxide nanoparticles Amrut. Here, commercially available 40 nm CuO NPs we Environmental Science: Nano 2014 Most Accessed Articles
Magnetic properties of the Synthesized Nanoparticles showed a Paramagnetic behavior. Cuprous oxide is p-type direct band gap II –VI semiconductor (3) with band gap of 2 eV and Cupric oxide has a monoclinic structure and presents p-type semiconductor behavior with … O ( Cuprous oxide) and CuO (Cupric Oxide) are two important oxide compounds of copper. Copper pipes © axe olga / fotolia.com. We report the synthesis of copper oxide (CuO) nanoparticles from Cu(NO3)2 through wet chemical precipitation method.
