| 摘 要： | 以亚硫酸氢钠(NaHSO3)和高锰酸钾(KMnO4)为原料,通过W/O乳状液模板技术制备了单分散纳米MnO2.用SEM和FT-IR手段对样品的形貌和成分进行了表征,并与均相反应制得的样品进行了比较.结果发现用本方法制得的纳米MnO2微粒单分散好,球形更规整,粒径大.FT-IR谱图也同时反映了粒径不同的两种样品所出现的量子尺寸效应.结合实验事实和样品特性,初步探讨了单分散纳米MnO2的形成机理.

| Abstract: | Mono-dispersed nanometer manganese dioxide was prepared from soldium hydrogen sulfite and potassium permanganate by using W/O emulsion as a template.The properties of product was characterized by employing SEM and FT-IR.The results showed that the product was of uniform,spherical,and mono-dispersed appearance.According to the experimental facts and characteristic of the product,the formation mechanism of mono-dispersed nanometer manganese dioxide was discussed. |
