Growth of N-doped BiOBr nanosheets on carbon fibers for photocatalytic degradation of organic pollutants under visible light irradiation

•The N-doped BiOBr nanosheets are immobilized on CFs by a solvothermal route.•The nanosheets are growth and compacted to form 3D interweave hybrid structure.•The composite fibers can be used for photocatalytic degradation of organic pollutants.

Aiming at effectively utilizing visible light and convenient separation of the photocatalysts from the water treatment system, the N-doped BiOBr photocatalysts with nanosheets structure and visible light photocatalytic properties have been immobilized on the surface of carbon fibers (CFs) by a facile solvothermal route. The morphology and structural properties of the resultant N-doped BiOBr/CFs hybrid structures were investigated by scanning electron microscopy (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The as-prepared N-doped BiOBr/CFs hybrids exhibited excellent photocatalytic activities for the degradation of organic pollutants (rhodamine B and methanol) under visible light irradiation.
