Hydrotalcite-like inorganic layers of Zn-Al, a host containing an organic moiety, 2,4-dichlorophenoxy-acetate, as a guest, was prepared by the spontaneous self-assembly method from an aqueous solution for the formation of a new layered organic-inorganic hybrid nanocomposite material. In this synthesis, the host- and guest-forming species were simultaneously included in the mother liquor, aged, and separated. Various Zn/Al ratios (R = 2, 3, and 4), concentrations of 2,4-dichlorophenoxyacetic acid (0.03-0.1 M), and pH (7 and 10) were studied to optimize the formation of the layered nancomposite. It was found that the optimum conditions for the formation of the nanocomposite were R = 4, pH 7, and concentration of 2,4-dichlorophenoxyacetic acid = 0.08 M. X-ray diffraction shows that this sample affords a nanolayered structure with a basal spacing of 24.6 A.
通过自发自组装法从水溶液中制备了一种含锌铝类水滑石无机层，其作为主体包含有机部分2,4 - 二氯苯氧基乙酸根作为客体，以形成一种新型层状有机 - 无机杂化纳米复合材料。在该合成过程中，主体形成物种和客体形成物种同时包含在母液中，经过陈化后分离。研究了各种锌/铝比（R = 2、3和4）、2,4 - 二氯苯氧基乙酸的浓度（0.03 - 0.1 M）以及pH值（7和10），以优化层状纳米复合材料的形成。结果发现，形成纳米复合材料的最佳条件为R = 4、pH 7以及2,4 - 二氯苯氧基乙酸浓度 = 0.08 M。X射线衍射表明，该样品具有层间距为24.6 Å的纳米层状结构。
