摘　　要：在微波辅助作用下制备了不同浓度的Zn O纳米材料.通过X-射线衍射(XRD)、紫外-可见漫反射(UV-Vis/DRS)、扫描电镜(SEM)等测试手段对其组成、结构和形貌等进行了表征.结果表明,产物合成过程中辅以微波后,Zn O纤锌矿晶型结构未发生明显变化,且形貌呈现较为规则的纳米棒状.在紫外光、可见光及微波辅射多模式光催化降解罗丹明B的实验中,所制备的不同浓度Zn O纳米材料均具有较好的光催化活性,其中,0.2 M Zn O的光催化活性最好.The different concentrations of ZnO were prepared under the effect of microwave-assisted. The composition, structure and morphology were well-characterized by X-ray powder diffraction （ XRD ） , UV-visible diffuse reflectance spectroscopy （ UV vis/DRS ） and scanning electron microscopy （ SEM ） . The results showed that the crystal structure of ZnO assisted by microwave irradiation during the synthesis process was not significantly changed, but the morphology was more regular. The prepared different concentrations of ZnO nano-materials had good photocatalytic activity in experiments of multi-mode photocatalytic degradation of rhodamine B under ultraviolet light, visible light and microwave-assisted irradiation, while the photocatalytic activity of 0.2 M ZnO was the best.
