英文摘要In this paper, a large scale and facile process was proposed for fabricating uniform and cheap Cu/Ag/Ag3PO4 core-shell coaxial nanowires at room temperature. Cu/Ag/Ag3PO4 ternary nanowire photo-catalysts were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and ultraviolet-visible diffuse reflectance spectra (DRS). Photocatalytic tests displayed that the Cu/Ag/Ag3PO4 heterostructures possessed a higher degradation rate of methylene blue than pure Ag3PO4 and P25 under visible light irradiation. The enhanced photocatalytic performance could be attributed to effective separation of photogenerated carriers driven by photoinduced potential difference generated at the metal-semiconductor heterojunction interface. Repetitive tests showed that the Cu/Ag/Ag3PO4 heterostructures maintained high stability over 5 cycles. This kind of cheap and high-efficient hybrid photocatalysts are expected to show considerable potential applications in pollution controlling. (C) 2016 Elsevier B.V. All rights reserved.
