摘要： 在采用水热-煅烧法制备了Bi3O4Cl纳米片的基础上，再通过水热法构建了微球状的Bi3O4Cl/BiOI复合光催化剂。通过X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、紫外-漫反射光谱（UV-Vis DRS）和光致发光（PL）光谱等测试手段对制备的光催化剂的结构与性能进行了表征。以甲基橙（MO）为目标降解物，对催化剂的光催化活性进行了评价。结果表明：Bi3O4Cl与BiOI复合后，增强了可见光的吸收，降低了光生载流子的复合率，因而导致了复合物的光催化活性的显著提升。

Abstract: Bi3O4Cl nanosheets were prepared by the hydrothermal-calcination method first, and then microspherical Bi3O4Cl/BiOI composite photocatalysts were prepared by the hydrothermal method. The structure and properties of the as-prepared photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS) and photoluminescence (PL) testing methods. Methyl orange was selected as the target degradation substance to evaluate the photocatalytic activity of the photocatalysts. The results showed that the composite of Bi3O4Cl and BiOI enhanced the absorption of visible light and reduced the recombination rate of photo-generated carriers, which resulted in a significant improvement in the photocatalytic activity of the photocatalysts.
