2010 WILEY-VCH Verlag Gmb The synthesis of colloidal nanoparticles (NPs) possessing hollow or core/shell structures has attracted a great deal of attention because these materials exhibit unique physical and chemical properties that allow them to be used in catalysis and drug delivery. These particles are typically produced using sacrificial templates, such as polystyrene or silica. Nevertheles...

Abstract Cuprous oxide (Cu2O) nanoparticles were successfully synthesized using cupric hydroxide gel as a precursor and glucose reductant. A well-dispersed was prepared by treatment of aqueous cuprous chloride with anion exchange resin. The average diameter the Cu2O 780 nm. Attenuated total reflectance Fourier transform infrared spectroscopy showed that polyethylene from resin present in powder...

A sensitive electrochemical sensor was developed using reduced graphene oxide RGO-Cu2O/Fe2O3 nanocomposite for 6-mercaptopurine detection based on a facile fabrication method. The surface morphology and structural composition of this evaluated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FT-IR) spectroscopy. screen-printed graphit...

Metal and metal oxides are widely used in industry, and to optimize their performance their surfaces are commonly functionalized by the formation of thin films. Self-assembled monolayers (SAMs) are deposited on metals or metal oxides either from solution or by gas deposition. The gas deposition enables the preparation of SAMs under very well controlled conditions in ultrahigh vacuum (UHV). Thio...

This study focused on the copper (I) oxide (Cu2O) that serves as an absorber layer, owing to its excellent optical properties, while titanium dioxide (TiO2) is a well-known material has superior properties in solar cell development. In this work, TiO2 nanorods layer was synthesised fluorine-doped tin (FTO) glass substrate by facile hydrothermal method followed stacking Cu2O using low-cost elect...

New Cu2O@TiO2 core-shell microspheres were successfully prepared for the first time in this paper. The XRD, N2 adsorption-desorption, SEM, TEM, EDX and XPS characterizations utilized to investigate physical chemical properties. liquid phase oxidation of naphthalene was also carried out test their catalytic performance. characterization results indicating that Cu2O firstly formed by hydrothermal...

Cu-oxide nanophases (CuO, Cu2O, Cu0) constitute highly potent nanoplatforms for the development of efficient Artificial Photosynthesis catalysts. The reducing conduction band edge d-electrons in Cu2O dictates its efficiency towards CO2 reduction under sunlight excitation. In present review, we discuss aspects interlinking stability photocorrosion (CuO/Cu2O/Cu0) nanophase equilibria, and perform...
