摘要

摘要: 通过化学沉淀法制备了BiOX（X=Cl、Br、I）光催化材料，并采用扫描电子显微镜、X射线衍射、X射线光电子能谱、氮气吸附-脱附和紫外-可见漫反射光谱等手段对其结构和性能进行了表征。结果表明：BiOBr具有由纳米片组成的花状纳米微球结构，形貌更立体，比表面积更大，且光吸收范围适中，展现出良好的可见光吸收能力，因此在氙灯照射下对NO的光催化降解效果最佳。此外，还探究了光照强度、NO流量和有无氧气条件对BiOBr降解NO性能的影响。实验结果表明：当光源距离为15 cm，NO流量为15 mL/min且有氧气存在时，BiOBr对NO的降解效果最佳，去除率达到58%。实验结果为BiOBr在光催化降解NO领域的应用提供了重要依据。

Abstract: BiOX （X = Cl， Br， I） photocatalytic materials were prepared by a chemical precipitation method. Their structures and properties were characterized using scanning electron microscopy， X-ray diffraction， X-ray photoelectron spectroscopy， nitrogen adsorption-desorption， and ultraviolet-visible diffuse reflectance spectroscopy. The results showed that BiOBr possesses a flower-like nanomicrosphere structure composed of nanosheets， which gives it a more three-dimensional morphology， a larger specific surface area， and a moderate light absorption range， resulting in superior visible light absorption. Consequently， BiOBr exhibited the best photocatalytic degradation of NO under xenon lamp irradiation. In addition， this study investigated the effects of light intensity， NO flow rate， and oxygen concentration on the NO degradation performance of BiOBr. The experimental results showed that the optimal NO removal rate of 58% was achieved under the conditions of a light source distance of 15 cm， an NO flow rate of 15 mL/min， and in the presence of oxygen. These findings provide an important experimental basis for the application of BiOBr in the photocatalytic degradation of NO.
