摘要
以醋酸铅和碘化钾为原料,通过在体系中添加乙醇胺、二乙醇胺和三乙醇胺,采用一步室温固相反应成功制备出羟碘铅(Pb(OH)I)纳米棒和菱形结构的PbI2/TEA(TEA为三乙醇胺)杂化物,利用XRD、IR、TG、SEM和元素分析对其组成、结构和形貌进行了表征。实验结果表明:乙醇胺、二乙醇胺和三乙醇胺,在醋酸铅与碘化钾固相反应体系中起到了双重作用。一方面充当反应原料,形成了Pb(OH)I和PbI2/TEA;另一方面充当软模板的作用,诱导产物形成了棒状和菱形结构。
Laurionite-type Pb（OH）I nanorods and rhombic PbI2 /TEA hybrid were synthesized by one-step, room temperature, solid-state reaction of lead acetate and potassium iodide in the presence of ethanolamine, diethanolamine and triethanolamine （TEA）. The chemical composition, structure and morphology features of products were investigated by XRD, IR, TG, SEM and elemental analyses respectively. The experimental results indicated that ethanolamine, diethanolamine and triethanolamine （TEA） play two important roles during the formation of products. On the one hand, they act as reactants, leading to the formation of Pb（OH）I and PbI2/TEA, on the other hand, they act as soft templates, which induce products to form rods and rhombic structures.
