Abstract
Aiming at effectively utilizing visible light and convenient separation of the photocatalysts from the water-treatment system, the N+S-codoped BiOBr photocatalysts with a three-dimensional (3D) open porous structure and visible-light photocatalytic performance have been immobilized on the surface glass fibers (GFs) by a facile solvothermal route. The morphologies and structure of the resultant samples were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT). The as-prepared samples exhibited excellent photocatalytic activities for degradation of rhodamine (RhB) under visible light irradiation. More than 98% RhB can be removed after irradiation for 60min under visible light. Furthermore, this hybrid material can be easy to separate from the water-phase system. This research provides a new route to access a visible-light induced and convenient separation photocatalyst with a high activity under mild conditions.
