Various characterization techniques such as Energy-dispersive x-ray spectroscopy (EDS), Ultraviolet Visible (UV–vis) Spectroscopy, diffraction (XRD), Transmission Electron Microscopy (TEM) and Fourier-transform Infrared (FTIR) Spectroscopy utilized to ...

In the last few decades, use of copper oxide nanoparticles (CuO NPs) has been increased significantly that eventually included as a growth stimulator. This makes it essential to examine their impact on several plants. study detailed here, we investigated effects CuO NPs growth, physiological efficiency, biochemical assays, and antioxidant system in mustard plant. Varying concentrations (0, 2, 4...

Stable alkyne-capped copper nanoparticles were prepared by chemical reduction of copper acetate with sodium borohydride in the presence of alkyne ligands. Transmission electron microscopic measurements showed that nanoparticles were well dispersed with a diameter in the range of 4e6 nm. FTIR and photoluminescence spectroscopic measurements confirmed the successful attachment of the alkyne ligan...

Wet chemistry was used to produce copper oxide nanoparticles (CuO NPs). The results indicated that most were bacillus-shaped and relatively uniform in size (less than 30 nm). effect of synthesized CuO NPs on wheat (Triticum aestivum L.) germination growth parameters studied compared bulk Cu. showed no significant difference obtained rate among all treatments. Bulk Cu additions significantly aff...

Abstract This work showed the preparation of Copper oxide nanoparticles (CuO NPs) from leaf extract Cinnamomum camphora (C.camphora) by a green synthetic method. To prepare CuO NPs, about 10 ml 0.01 M copper sulphate and 30 C.camphora were mixed heating for 60 min at temperature 80 °C. Various techniques such as x-ray diffraction analysis (XRD), Energy-dispersive spectroscopic (EDS), Fourier-tr...

Single crystalline nanoparticles of copper oxide (CuO) having almost uniform particle size of ~40±10nm have been synthesized by a facile and versatile route. The technique employed is free from toxic solvents, organics, and amines, and is based on a simple reaction of copper powder and de-ionized water (DI) at very low temperatures of 180oC. The morphology, chemical composition, and crystalline...

In recent years, the green chemistry based-approach for synthesis of nanoparticles has shown tremendous promise as an alternative to costly and environmentally unfriendly chemically synthesized nanoparticles. this study, copper oxide (CuO NPs) were through a approach using water extract papaya (Carica L.) peel biowaste reducing well stabilizing agents, (II) nitrate trihydrate salt precursor. Th...

The current study aimed to examine the overall feasibility of the use of copper oxide nanoparticles (CuO-NPs) as a catalyst in ozonation process for the removal of benzene from aqueous solutions under experimental conditions. This experimental study was conducted on a laboratory scale reactor in a semi-batch mode. The effect of critical operating parameters such factors as pH, concentration of ...
