Resumen

The BiOBr_xI_1−x/BiOBr heterojunction structural photocatalyst was constructed successfully in this work and it was formed by the BiOBr_xI_1−x solid solution coupling with the BiOBr monomer, which was determined by efficient characterizations. For the photocatalytic property, The BiOBr_xI_1−x/BiOBr could degrade some organic pollutants efficiently and the oilfield produced waste water treatment efficiency of it was ideal. The reason for its enhanced photocatalytic property was also explored. Through ESR tests, trapping experiments and other efficient methods, the enhanced molecular oxygen activation capacity of induced ¹O₂ and O₂^[rad]− photogeneration by BiOBr_xI_1−x solid solution structure and heterostructure in one photocatalyst was confirmed, respectively. This work provided a new thought for enhanced molecular oxygen activation capacity of bismuth oxyhalide photocatalysts.
