Ultrathin copper oxide (CuO) nanorods with diameters of ∼3.6 nm were obtained in one step using oleylamine (OAm) as both the solvent and the surface controller. The oriented attachment is responsible for the formation of the ultrathin CuO nanorods. Furthermore, this ultrathin nanostructure catalyst exhibited excellent activity and high styrene oxide yields in styrene epoxidation.

Herein, the aqueous extract of Portulaca oleracea has been used as a safe, cheap, eco-friendly, and applicable scale-up method to bio-fabricate copper oxide nanoparticles (CuO-NPs). The character CuO-NPs were determined using UV-vis spectroscopy, Fourier transform infrared (FT-IR), X-ray diffraction (XRD), Transmission electron microscopy (TEM), Energy dispersive X-ray(EDX), Dynamic light scatt...

Green methods of synthesizing nanoparticles are safer than chemical and physical methods, as well being eco-friendly cost-efficient. In this study, we use copper oxide (CuO NPs) fabricated with Sesbania grandiflora (Sg) (Hummingbird tree) leaves to test the effectiveness green methods. The attained Sg-CuO NPs optical nature is characterized by UV-Vis spectroscopy Differential Reflectance Spectr...

The fate of nanoparticles (NPs) in soil under relevant environmental conditions is still poorly understood. In this study, the mobility two metal-oxide (CuO and TiO2) contrasting agricultural soils was investigated water-saturated columns. transport TiO2 CuO-NPs were assessed six with three different textures (from sand to clay) contrasted organic matter (OM) contents for each texture. very low...

Two different kinds of CuO nanoparticles (NPs) namely CuO nanorods (PS2) and multi-armed nanoparticles (P5) were synthesized by wet and electrochemical routes, respectively. Their structure, morphology, size and compositions were characterized by SEM, EDX and XRD. The NPs demonstrated strong bactericidal potential against Bacillus anthracis cells and endospores. PS2 killed 92.17% of 4.5 × 10(4)...

The increase of copper oxide nanoparticle (CuO-NP) utilization in industry during recent years has resulted in their entry into aquatic ecosystems. In light of this fact, we have studied the toxicity of CuO-NPs at various concentrations on Chlorella vulgaris using an algal growth inhibition test (OECD201). Chlorella vulgaris was grown in positive Zander (Z-8 + N) media in a growth chamber. Afte...

Supported copper oxide nanoparticles have attracted considerable attention as active and non-precious catalysts for many catalytic oxidation reactions. Herein, mesoporous xCuO-TiO2 nanotube catalysts were fabricated, and their activity and kinetics toward CO oxidation were studied. The morphology and structure of the prepared catalysts were systematically studied using SEM, TEM, EDS, EDX, XRD, ...

Abstract This paper reports the preparation of copper(I) oxide nanoparticles deposited on yttrium and copper(II) in presence acerola white willow extracts. Through use natural compounds, it was possible to modify surface Y 2 O 3 CuO carriers allowing Cu be a greater extent, thus improving antibacterial properties materials. nanoparticles, by being carrier, enable an increase contact with microo...
