为提高可见光催化性能，制备了量子点敏化的CdS-Bi 2 WO 6复合光催化剂。采用X射线衍射（XRD）、扫描电镜（FE-SEM）、透射电镜（TEM）、紫外-可见漫反射光谱（DRS）对产物进行了表征。以可见光（λ > 420 nm）照射下降解甲基橙子为目标，研究了量子点敏化的CdS-Bi 2 WO 6样品的光催化活性。DRS结果表明，CdS-Bi_2 WO_6样品在可见光区有较强的吸收，并发生了红移。经量子点CdS敏化后的Bi 2 WO 6样品对橙子的降解表现出较高的效率。本研究为利用可见光处理有机污染物提供了一种途径。
Novel quantum dots sensitized CdS-Bi2WO6composite photocatalysts were synthesized to improve the visible-light-driven photocatalytic performance. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) UV–vis diffuse reflectance spectra (DRS). The photocatalytic activities of QDs sensitized CdS-Bi2WO6samples were investigated based on the decomposition of methyl orange under visible light irradiation (λ > 420 nm). The DRS results revealed that CdS-Bi2WO6samples have a red shift and stronger absorption in the visible light region. After being sensitized by quantum dots CdS, the Bi2WO6samples showed the high efficiency for the degradation of methyl orange. This study may provide an approach to treatment of organic pollutants by using visible light.
