摘要：

Ag3PO4 is an excellent photocatalyst with high efficiency and quantum yield, but suffers from the fast recombination of photogenerated electron-hole pairs and photo-corrosion. Hereby, the highly efficient and stable visible-light-driven Pr6O11/Ag3PO4/Pt photocatalyst were prepared via a three-step wet chemical approach. The as-prepared Pr6O11/Ag3PO4/Pt composite was characterized by X-ray diffraction, US-vis diffuse reflectance spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, photoluminescence spectra and transient photocurrent as well. Comparing with single Pr6O11 or Ag3PO4, the prepared Pr6O11/Ag3PO4/Pt composite exhibited much higher photocatalytic activity and stability for the degradation of Rhodamine B under visible light irradiation (>420 nm). The enhanced photocatalytic performance of Pr6O11/Ag3PO4/Pt composite has been attributed to the efficient separation of photo-generated electron-hole pairs through a scheme system composed of Pr6O11, Ag3PO4 and Pt.
