采用简单的溶剂热方法制备了具有丰富氧空位的卤氧化铋分级结构的微米花（BiO 1-xCl分级结构微米花）。与纯BiOCl分级纳米材料相比，BiO 1-xCl分级微米花在可见光照射下对典型有机染料和抗生素的降解表现出优异的光催化性能。令人兴奋的是，这种上级光催化活性被保持用于分解复杂的三元混合抗生素。在三元混合抗生素溶液中，30 min内几乎100%的抗生素被光降解。这种高的光催化活性来源于层次微花的体缺陷。
Well-defined bismuth oxyhalide hierarchical microflowers with rich oxygen vacancies (named BiO1-xCl hierarchical microflowers) were prepared by a simple solvothermal strategy. The BiO1-xCl 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.
