Abstract

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.
