以ZnSO_4和NaOH为原料,强碱性阴离子交换树脂为模板,采用反应性离子交换法一步合成了高纯纳米ZnO晶体,并运用扫描电子显微镜、X射线衍射和紫外-可见光谱等技术对样品进行了表征,初步探讨了合成机理.结果表明,制得的纳米ZnO晶体呈一维棒状,它在树脂表面的形成过程与znSO_4的初始浓度密切相关.该ZnO样品对光催化降解甲基橙具有较高的活性和循环使用性能.

Nano-crystalline ZnO particles were synthesized by a reactive ion exchange procedure using ZnSO_4 and NaOH as precursors and a strong basic anion exchange resin as substrate. The precursors and ZnO samples were characterized by scanning electron microscopy, X-ray diffraction, and UV-Vis spectroscopy. The ZnO particles were club shape, and the synthesis process depended on the reactant concentration of ZnSO_4 in the solution. The ZnO powders had high photocatalytic activity and stability for the gradation of methyl orange.
