为了有效地利用可见光并使光催化剂与水处理系统分离，采用简单的溶剂热方法将具有纳米片结构和可见光催化性能的n掺杂BiOBr光催化剂固定在碳纤维表面。采用扫描电镜（SEM）、透射电镜（TEM）、x射线衍射（XRD）和x射线光电子能谱（XPS）研究了n掺杂BiOBr/CFs杂化结构的形貌和结构性质。制备的n掺杂BiOBr/CFs杂化物在可见光下对有机污染物（罗丹明B和甲醇）的降解表现出优异的光催化活性。
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.
