Abstract

It is critical to enhance the photocatalytic performance of BiOBr through appropriate strategies. Two BiOBr samples with different water (W) and ethylene glycol (EG) solvents have been synthesized. BiOBr-EG presents a 3D nest-like morphology composed of nanoplates, prominently emphasizing (110) facets. In contrast, BiOBr-W displays 2D microplates with exposed (102) facets. Notably, BiOBr-EG exhibits a degradation rate 7.4 times faster and removal efficiency of Enrofloxacin (ENR) 2.2 times greater than that of BiOBr-W. Additional investigations reveal that ·O₂⁻ plays a dominant role in the degradation process. Finally, the degradation pathways are explored through DFT calculation and HPLC-MS methods.

全面研究溶剂对 BiOBr 合成的影响：了解恩诺沙星的光催化机理及其降解途径

通过适当的策略提高 BiOBr 的光催化性能至关重要。我们合成了两种以不同水（W）和乙二醇（EG）为溶剂的 BiOBr 样品。BiOBr-EG 呈现出由纳米板组成的三维巢状形貌，突出的是 (110) 面。相比之下，BiOBr-W 则呈现出二维微板，具有暴露的（102）面。值得注意的是，BiOBr-EG 的降解速度是 BiOBr-W 的 7.4 倍，恩诺沙星（ENR）的去除效率是 BiOBr-W 的 2.2 倍。其他研究表明，-O2- 在降解过程中起主导作用。最后，通过 DFT 计算和 HPLC-MS 方法探索了降解途径。
