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 ***,we report the facile synthesis of a heterojunction photocatalyst composed of basic bismuth nitrate(BiON)and BiOCl_(0.9)I_(0.1) using a simple room-temperature hydrolysis *** results demonstrate that the BiON/BiOCl_(0.9)I_(0.1) 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 ***,the unique three-dimensional microsphere morphology of the synthesized composite enhances its specific surface area and light absorption,further enhancing its photocatalytic *** the tetracycline(TC)photodegradation reaction as a model reaction,the catalyst could degrade 88%of TC in just 25 ***,this work provides a promising strategy for the facile and low-cost synthesis of heterogeneous photocatalytic degradation materials.
