采用水热晶化法成功制备了镉离子掺杂的ZnWO 4纳米棒。采用X射线衍射（XRD）、能谱分析（EDS）、扫描电镜（SEM）和透射电镜（TEM）等技术对产物进行了表征。对水溶液中罗丹明B（RhB）的光催化降解实验结果表明，镉离子掺杂显著提高了ZnWO 4纳米棒的光催化效率。当Cd/Zn原子比为0.06时，在pH为8的条件下制备的Cd掺杂ZnWO 4纳米棒在紫外光照射下对罗丹明B的光降解活性最好。(C)2010年爱思唯尔。All rights reserved.
The ZnWO4 nanorods doped with cadmium ions have been successfully synthesized by a hydrothermal crystallization process. The products were characterized in detail by multiform techniques: X-ray diffraction (XRD), energy dispersive X-ray analysis (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results of the photocatalytic degradation of rhodamine B (RhB) in aqueous solution showed that cadmium ions doping greatly improved the photocatalytic efficiency of ZnWO4 nanorods. The Cd-doped ZnWO4 nanorods with atomic ratio of Cd to Zn being 0.06 had the best activity in photo-degradation of RhB in aqueous solution under UV light irradiation, when the nanorods have prepared at pH 8.
