The present work describes the synthesis of copper(II) oxide nanoparticles (NPs) with high surface area (52.11 m2/g) and its Ni(II) adsorption efficiency from contaminated water at room temperature. Copper (II) NPs are able to remove as 93.6 per cent 93.7 using 500 ppb & 1000 initial concentration nickel near-neutral pH respectively. CuO is very much effective more than 75 over a wide range...

In this work, copper oxide nanoparticles have been synthesized via extractive Rosmarinus Officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (CH3COO)2Cu+H2O individually as Cu sources. It was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0C. Powder X-ray Diffrac...

the external and interlamellar spaces of montmorilonite (mmt) were used as solid support for synthesis of cuo nanoparticles (nps) at room temperature by the chemical reduction method. in this project, copper nitrate plus water (cu(no3)2. xh2o) and sodium hydroxide (naoh) were used as copper precursor and reducing agent respectively. then, mmt/cu2+ nanocomposites were stabilized with different r...

The Caspian trout is an endangered and quite vulnerable fish, considered for a natural protection program in the southern area of the Caspian Sea. Copper oxide nanoparticles (CuO-NPs) are toxic substances, which induce oxidative stress, not to mention other pathophysiological states. The toxicity of nanoparticles on fish needs more characterization for short- and long-term effects.  Thus, the p...

Copper oxide supported on γ-alumina nanoparticles were prepared and were well characterized. In this study catalytic activities of the supported copper oxide for oxidation of cyclohexene to 2-cyclohexene-1-ol, 2-cyclohexene-1-one and cyclohexene oxide with TBHP and H2O2 as the oxidant, in the liquid phase were considered. For the CuO/γalumina nanocomposites, acetonitrile as the solvent was empl...

The toxicity of CuO nanoparticles (CuO NPs) to human hepatocarcinoma (HepG2) cells was investigated in this study. CuO NPs (1 40 mg/L) had significant toxicity to HepG2 cells. The antioxidant N-acetyl-L-cysteine (NAC) significantly reduces the cytotoxicity induced by the CuO NPs, supporting the hypothesis that oxidative stress contributes to the cytotoxicity of CuO NPs. To further explore the o...

Copper oxide nanoparticles were synthesized using black tea extract and copper nitrate as thecopper source by the green method at different calcination temperatures. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of CuO nanoparticles without using any organicchemicals. The synthesize...

Copper oxide (CuO)-decorated cerium oxide (CeO₂) nanoparticles were synthesized and used to detect glucose non-enzymatically. The morphological characteristics and structure of the nanoparticles were characterized through transmission electron microscopy, X-ray photoelectron spectroscopy, and X-ray diffraction. The sensor responses of electrodes to glucose were investigated via an electrochemic...

Copper nanoparticles have been deposited on silicon surfaces by a simple galvanic displacement reaction, and rapid thermal annealing has been performed under various atmospheric conditions. In spite of the general tendency of the agglomeration of nanoparticles to lower the surface energy at elevated temperatures, our plan-view and cross-sectional transmission electron microscopy (TEM), energy d...

A rational integration of 1D metallic nanotubes and oxide nanoparticles has been demonstrated as a viable strategy for the production of both highly stable and efficient anodes for lithium ion batteries. We encapsulated copper oxide (CuO) nanoparticles in ultra-long metallic copper nanotubes with engineered interspaces, and explored their electrochemical properties. Such a hierarchical architec...
