| Abstract: | Pricky star-like cupric oxide with submicrometer sizes was successfully synthesized by the hydrothermal route using methenamine as precipitant in the presence of cationic gemini surfactant C16H33(CH3)2N＋(CH2)4N＋(CH3)2C16H33]?2Br－ (16-4-16). The as-prepared products were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscope (TEM). The as-prepared cupric oxide had monoclinic structure. The effects of concentrations of gemini surfactant, reaction temperature and reagents on the sample morphology were investigated. |
