Abstract
Rose-like Cu2O nanoflowers have been synthesized by polyvinylpyrrolidone K30 (PVP K30)-assisted hydrothermal method. Here, copper sulfate CuSO4 and sodium hydroxide NaOH were used as raw materials. The synthesized Cu2O powders were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). XRD pattern exhibited the nanocrystalline nature with cubic structure for the synthesized nanostructures. FESEM images indicated that the rose-like Cu2O nanostructures are composed of many nearly rectangular shape nanosheets in size of about 1–2 micrometers in width and length and approximate 50–60 nm in thickness. Analysis results reveal that PVP K30 plays a vital role in formation of rose-like Cu2O nanoflower in this work. The probable formation mechanism of rose-like Cu2O nanoflower was discussed.
