| 摘 要： | 采用水热法,以硝酸锌为原料,分别以四氟硼酸钠、N-丁基吡啶六氟磷酸盐和溴化1-乙基-23,-二甲基咪唑离子液体为导向剂合成了具有次级结构的扇面状、微球状和实心双螺帽状三种形貌的氧化锌,利用XRD和SEM对其结构和形貌进行了表征,研究了其荧光特性及对甲基橙的光催化活性.发现微球状ZnO在可见光区具有远远强于其它两种形貌ZnO的荧光.不同形貌的ZnO对甲基橙的光催化活性与商品TiO2(P25)的活性差别不大,其中扇面状ZnO的活性最高,实心双螺帽状ZnO次之,微球状ZnO活性最差.

| Abstract: | In the present paper,three zinc oxides with hierarchical structures and various morphologies,flabellate,microspheral and solid double screw cap-like,were synthesized by hydrothermal method where zinc nitrate was used as the raw material,and NaBF4,C9H4F6NP and C7H13BrN2 ionic liquids as directing agents,respectively.The X-ray diffraction(XRD) and scanning electron microscopy(SEM) were used to characterize their structures and morphologies.Fluorescence and photocatalytic activities on methyl orange were inves... |
