以WO_3和KOH为原料,采用水热法成功制备了K_(10)W_(12)O_(41)·11H_2O纳米棒状材料.利用X射线衍射(XRD)、扫描电镜(SEM)等手段对产物物相和形貌进行了表征.探讨了不同水热时间对合成K_(10)W_(12)O_(41)·11H_2O的形貌及光催化性能的影响.研究结果表明,当水热时间为12h时,一维纳米棒状形貌的K_(10)W_(12)O_(41)·11H_2O具有更高的光催化效率,紫外50min对亚甲基蓝的降解效率可达75%.
The K_ (10) W_ (12) O_ (41) · 11H_2O nanorod materials were successfully prepared by hydrothermal method using WO_3 and KOH as raw materials.The structures of the products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) Phase and morphology were characterized.The effects of different hydrothermal time on the morphology and photocatalytic activity of K_ (10) W_ (12) O_ (41) · 11H_2O were investigated.The results show that when the hydrothermal time is 12h K_ (10) W_ (12) O_ (41) · 11H_2O with one-dimensional nanorod morphology has higher photocatalytic efficiency, and the degradation efficiency of methylene blue can reach 75% after 50 min UV irradiation.
