A series of CuO-Cu2O/TiO2 nanocomposite samples were prepared by the sol-gel method. Before applying the sol-gel method, the Cu(OH)2 nanostructure on Cu powders were formed by in-situ solution treatment. The samples were characterized through some techniques and the photocatalytic performance of CuO-Cu2O/TiO2 nanocomposites for gas-phase 2-propanol photo-oxidation under UV and sunlight type ill...

A series of copper-based systems containing two different nanocomposites (Cu2O/CuO and Cu2O/Cu) was synthesized by the egg white assisted auto-combustion route. This method distinguished simplicity its steps, low cost, one-pot synthesis process at temperature and, short time. The characterization as prepared carried out using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning ...

A nanocomposite comprising cerium oxide nanoparticles (CeO2 NPs) and polypyrrole (PPy) was fabricated onto a microelectrode for cholesterol sensing application. The oxidase (ChOx) immobilized on the CeO2 NPs/PPy/electrode by physical adsorption route. structure morphology of NPs/PPy were characterized X-ray diffraction, field emission scanning electron microscopy, energy dispersive spectroscopy...

Abstract The current work aims to improve the metal oxide characteristics for mosquito control. Un-doped and Y-doped CuO have been synthesized by simple chemical route. Structural, composition, morphological properties were characterized XRD, Raman spectra, EDX, SEM, TEM techniques. obtained results revealed that was strongly affected Y 3+ support, in which crystallite size decreased, surface a...
