Abstract In this paper, CdMoO4 photocatalyst with enhanced sunlight-driven photocatalytic performance was prepared by a microwave hydrothermal method with the assistance of sodium dodecylbenzenseulfonate (SDBS). The photocatalysts were characterized by powder X-ray diffraction (XRD), Brunauer-Emmett-Tellermethod method (BET), surface photovoltage spectroscopy (SPS), scanning electron microscopy (SEM), and UV-Vis diffuse reflectance spectroscopy (DRS). The photocatalytic activities of the photocatalysts were evaluated by the decay of rhodamine B (RhB) and methylene blue (MB) aqueous solution under simulated sunlight irradiation. The results demonstrate that adding SDBS into the reaction system increases the specific surface area, enhances the photo-induced charge separation rate of CdMoO4 and the formation of ·O2–. The photocatalytic activity of SDBS-CdMoO4 is higher than that of the reference CdMoO4, originating from the efficient separation of photo-induced charge pairs and increased specific surface area.

SDBS辅助微波水热法制备CdMoO 4 的太阳光驱动光催化性能大幅增强

摘要 本文在十二烷基苯磺酸钠（SDBS）的辅助下，通过微波水热法制备了具有增强的太阳光驱动光催化性能的CdMoO4光催化剂。通过粉末X射线衍射（XRD）、Brunauer-Emmett-Teller方法（BET）、表面光电压光谱（SPS）、扫描电子显微镜（SEM）和紫外-可见漫反射光谱（DRS）对光催化剂进行表征。通过模拟阳光照射下罗丹明B（RhB）和亚甲蓝（MB）水溶液的衰变来评估光催化剂的光催化活性。结果表明，在反应体系中加入SDBS 增加了比表面积，提高了CdMoO4 的光致电荷分离率和·O2-的形成。
