摘要:

以单一和混合锌盐为锌源, 氢氧化钠为沉淀剂, 丙氨酸和离子液体(IL)为表面活性剂, 通过水热法制备了不同形貌的分级结构氧化锌粉末. 通过X射线衍射仪(XRD)、 扫描电子显微镜(SEM)、 红外光谱仪(IR)和紫外-可见分光光度计(UV-Vis)对样品进行了表征, 并探讨了锌源(单锌盐、 混合双锌盐及三锌盐)、 离子液体种类及用量、 丙氨酸用量和温度等变量对产物形貌的影响, 推测了在分级结构氧化锌形成过程中阴离子对样品形貌的调控作用.

Abstract:

The hierarchical-structure ZnO with different morphologies were fabricated by the hydrothermal method respectively using single and mixed zinc salts as the zinc source, sodium hydroxide as the precipitant, alanine and ionic liquid(IL) as the surfactant. The samples were characterized by XRD analysis, SEM observation, IR and UV-Vis spectrometry. The influential factors of the sample morphology were discussed, which included the zinc source(single, double and three zinc salts), the kind and dosage of ionic liquid, the dosage of alanine and temperature, etc. The modulation of anionic on sample morphology was speculated in the formation process of the ZnO with hierarchical structure.

Key words: ZnO, Hierarchical structure, Hydrothermal method, Morphology
