Synthesis of New Zn-containing Derivative by Multi-step Ion-exchanges
Source abstract
Abstract
对层状钙钛矿型化合物SrBi 2 Nb 2 O 9 依次进行H + /(BiO) + , 四甲基铵离子TMA + /H + , 及锌氨络离子Zn(NH 3 ) 4 2+ /TMA + 多步离子交换而获得含Zn衍生物. X射线衍射(XRD)结果显示出质子化产物和含Zn衍生物的衍射图谱与前驱物SrBi 2 Nb 2 O 9 的层状结构上的差异. 组成分析表明, 前驱物质子化后, Bi原子几乎全被抽出, 但也有少量的Sr损失. 紫外?可见吸收(UV-Vis)测量发现, 含Zn衍生物的紫外吸收边比质子化产物和前驱物的紫外吸收边明显向高能方向移动.
