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.
