Decolorization of rhodamine B photocatalyzed by Ag3PO4/Bi2WO6 nanocomposites under visible radiation

Heterostructure Ag3PO4/Bi2WO6 nanocomposites were synthesized by precipitation-deposition method. X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) spectroscopy and UV-visible spectrophotometry revealed that cubic Ag3PO4 nanospheres with <20 nm diameter were supported on orthorhombic Bi2WO6 nanoplates and that Ag3PO4/Bi2WO6 nanocomposites exhibited more enhanced photodegradation of rhodamine B than pure Bi2WO6.
