以Zn(Ac)2·2H2O和NaOH为反应物,以离子液体1-十二烷基-3-甲基咪唑四氟硼酸盐[C12mim][BF4]水溶液为反应介质,80℃下制得ZnO纳米棒。采用透射电子显微镜(TEM)、X射线衍射(XRD)和紫外可见吸收光谱(UVVis absorption spectra)对纳米ZnO的形貌和结构进行了表征,以有机染料亚甲基蓝溶液为光催化反应模型降解物,考察纳米ZnO的光催化性能。结果表明,制备出的纳米氧化锌呈棒状,宽约10nm,长约160nm,为六方纤锌矿结构。紫外灯照射120min后,对亚甲基蓝溶液的降解率可达到86.3%。
Using Zn (Ac) 2 · 2H2O and NaOH as reactants and ionic liquid 1-dodecyl-3-methylimidazolium tetrafluoroborate [C12mim] [BF4] ZnO nanorods. The morphologies and structures of ZnO nanowires were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV-Vis absorption spectra. The organic dye methylene blue solution was used as the photocatalytic degradation model. Photocatalytic Properties of Nanometer ZnO. The results show that the ZnO nanorods are rod-shaped, with a width of 10nm and a length of 160nm, which is hexagonal wurtzite structure. After 120min UV irradiation, the degradation rate of methylene blue solution can reach 86.3%.
