Synthesis and Characterization of Cu2O/TNTs nanocomposites

摘要

Cu2O/TNTs(Titanium-based Nanotubes) composites were prepared by a simple “soak-deoxidize” method by using hydrazine hydrate as the reducing agent. The Cu2O/TNTs composites particles was made by changing pH and the mol ratio of Cu2+:N2H4H2O. The obtained composites were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), UV-Vis Diffuse reflectance spectra(DRS). The results of UV-Vis diffuse reflectance spectra indicate that the absorption edge of Cu2O/TNTs shows a shift to visible-light region, followed by an obvious absorption peak at 500–700 nm.
