以硫酸锌为锌料,采用低温液相的方法合成了具有花状结构的纳米ZnO,并用XRD和SEM对样品进行了测试表征;考察了不同条件下制备的样品降解甲基橙的性能,结果表明:以碳酸钠做沉淀剂及3%的油酸钠做表面活性剂时所得样品在2 h对甲基橙的降解率可达90%以上。
以硫痠鋅為鋅料,採用低溫液相的方法閤成瞭具有花狀結構的納米ZnO,併用XRD和SEM對樣品進行瞭測試錶徵;攷察瞭不同條件下製備的樣品降解甲基橙的性能,結果錶明:以碳痠鈉做沉澱劑及3%的油痠鈉做錶麵活性劑時所得樣品在2 h對甲基橙的降解率可達90%以上。

Flower-like structure of nano ZnO was synthesized by aqueous method at low-temperature with zinc sulfate as raw material in this paper.The shape and structure of the final products were characterized by XRD and SEM.The performance of the degradation of methyl orange was investigated for samples prepared under different conditions.The results indicated that the samples which were prepared with sodium carbonate as precipitation agent and sodium oleate as surfactant for the degradation of methyl orange rate can reach more than 90%in two hours.
