AbstractVisible-light-driven (VLD) BiOI/BiOBr heterostructure films with hierarchical microstructure have been firstly fabricated on 304 stainless steel wire mesh (304SSWM) substrates through a novel ion-exchange method using the BiOI film as precursor. The concentration of tetrabutylammonium bromide (TBAB) is the key factor to control the composition and microstructure of BiOI/BiOBr films. Physical, chemical, and optical properties of BiOI/BiOBr heterostructure films were characterized by X-ray diffraction, scanning electron microscope, energy dispersive X-ray spectroscopy, high resolution transmittance electron microscopy, X-ray photoelectron spectroscopy, UV-vis diffuse reflectance absorption, and fluorescence spectrophotometer, respectively. The VLD photocatalytic ability of the BiOI/BiOBr heterostructure film coated 304SSWM was studied by degrading rhodamine B and pIRES2-EGFP plasmid as target water organic pollutants and pathogenic bacteria genetic materials. The BiOI/BiOBr heterostructure film coated 304SSWM fabricated with 50 mM TBAB has excellent photocatalytic activity, stability, and reusability in the cycled experiments. The reasons for these unique features can be ascribed to the formation of heterojuction structure and the open framework structure of the 304SSWM. The current work can provide new strategies to construct novel VLD photoactive functional films for water purification and disinfection.
