摘要
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%.
Using KOH and WO3 as raw materials,K10W12O41·11H2O nanorod was successfully synthesized via controlling reaction time.Influences of reaction time on photocatalytic performance of K10W12O41·11H2O nanorod were researched by X-Ray Diffraction（XRD）,Scanning Electron Microscope（SEM）.Results indicate that the size of K10W12O41·11H2O nanorod was about 200 nm in width and 3～10μm in length and the K10 W12O41·11H2O nanorod has higher photocatalytic activity to degrade Methylene blue,which degradation efficiency reaches 75% under UV irradiation for 50 min.
