| 英文摘要 | Biofilm plays an important role on microbial corrosion and biofouling in marine environments. Inhibiting biofilm formation on construction surfaces is of great importance. Photocatalytic material with visiblelight response, especially BiVO_4, is regarded as a promising material for biofilm inhibition due to its green biocidal effect and high antibacterial efficiency. Approaches which can immobilize the photocatalytic particles onto metal surfaces with high mechanical strength are requisite. In this study, zinc matrixes were served as carriers for BiVO_4 particles. The BiVO_4-inserted zinc matrixes were successfully obtained by ultrasound assisted electrodeposition. The insertion content of BiVO_4 showed positive correlation with ultrasound power. Highly enhanced biofilm inhibition properties were obtained by BiVO_4 inserted zinc·matrixes with an over 95 % decreased bacterial coverage. It was proved that O_2~(-)(chief) andOH(subordinate) radicals were responsible for the high biocidal performance. Possible antibacterial mechanism was proposed, indicating that the photoinduced holes would both attack zinc crystals to generate active electrons to form O_2~(-) radicals, and react with H_2 O to generate·OH, finally. Furthermore, corrosion resistance of the matrixes was proved to be stable due to the insertion of BiVO_4. This study provides a potential application for photocatalyst in marine antifouling and anti-biocorrosion aspects. |
