外文摘要：Hierarchical heterostructures have emerged as promising candidates for the efficient photocatalytic degradation of antibiotics owing to their matched energy levels and tunable absorption bands.Herein,we report the facile synthesis of a heterojunction photocatalyst composed of basic bismuth nitrate(BiON)and BiOCl0.9I0.1 using a sim-ple room-temperature hydrolysis method.Our results demonstrate that the BiON/BiOCl0.9I0.1 composite exhibits superior photodegradation performance compared to pure-phase materials owing to the catalytic enhancement at the heterointerface and the effective separation of the photogenerated carriers.Moreover,the unique three-dimensional microsphere morphology of the synthesized composite enhances its specific surface area and light absorption,further enhancing its photocatalytic activity.In the tetracycline(TC)photodegradation reaction as a model reaction,the catalyst could degrade 88％of TC in just 25 min.Overall,this work provides a promising strategy for the facile and low-cost synthesis of heterogeneous photocatalytic degradation materials.
