Abstract

Abstract : Well-defined 3D BiOCl hierarchical microflowers with oxygen vacancy have been fabricated by a simple polyalcohol solvothermal method; the light adsorption can be extended across the whole visible region. Abstract : Well-defined bismuth oxyhalide hierarchical microflowers with rich oxygen vacancies (named BiO1− x Cl hierarchical microflowers) were prepared by a simple solvothermal strategy. The BiO1− x Cl hierarchical microflowers showed excellent photocatalytic properties for the degradation of typical organic dyes and antibiotics under visible light irradiation, compared with pure BiOCl hierarchical nanomaterials. Excitingly, this superior photocatalytic activity was maintained for decomposing the complex ternary mixed antibiotics. Almost 100% antibiotics can be photodegraded within 30 min in the ternary mixed antibiotic solution. This high photocatalytic activity originates from the bulk defects of hierarchical microflowers.
