| 摘要 | beta-AgVO3/BiVO4 composite visible light driven (VLD) photocatalytic antibacterial materials with a heterojunction structure were synthesized through a simple one-pot hydrothermal approach. The synthesized samples were characterized by X-ray diffraction, scanning electron microscopy, high resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray photoelectron spectroscopy, photoluminescence spectra, and UV-visible diffuse reflectance spectra techniques, respectively. beta-AgVO3/BiVO4 composite materials exhibit enhanced photocatalytic antibacterial activities against typical marine fouling bacteria (Pseudomonas aeruginosa) under visible light irradiation, which can be attributed to the involving of beta-AgVO3 to form a heterojunction structure. The heterojunction greatly increases the separation extent and the lifetime of the photogenerated charges in the composite material. The 20% beta-AgVO3/BiVO4 sample has the best VLD photocatalytic antibacterial performance. Under 30 min visible light irradiation, its antibacterial rate can reach 99.99%. The superoxide radical (center dot O-2(-)) and holes (h(+)) are main active species in the VLD photocatalytic antibacterial process on the basis of the radical trapping experiment results. Furthermore, a high photocatalytic antibacterial activity can be kept after 5 cycles, suggesting high stability of beta-AgVO3/BiVO4. Materials obtained in the present work can be potentially applied in practical antibacterial fields. (C) 2018 Elsevier B.V. All rights reserved. |
