▎ 摘 要
In this study, reduced graphene oxide-BiPO4 (RGO-BiPO4) nanocomposite was synthesized successfully via a one-pot solvothermal method using graphene oxide and bismuth nitrate as precursors and glycerin as solvent at 200 degrees C for 1 h. The morphology and structure of as-prepared nanocomposite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), surface enhanced Raman spectroscopy (SERS) and UV- visible spectrum. The photocatalytic activity of the nanocomposite was evaluated by the photodegradation of Rhodamine B (RhB) dye under UV irradiation. The experimental results showed that RGO-BiPO4 nanocomposite possessed higher photocatalytic activity than that of pure BiPO4. RhB could be decomposed about 87.5% within 2 h. Under the same conditions, only 45.7% of RhB dye could be decomposed by BiPO4. The enhancement of photocatalytic activity could be attributed to the effective charge separation due to the electron-accepting and transporting properties of RGO.
