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.
