摘要

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。

Comprehensive investigation of solvent effects on BiOBr synthesis: Understanding the photocatalytic mechanisms of enrofloxacin and its degradation pathway

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.
