以ZnCl 2和Sn（OC 4 H9）4复合物为无机前驱体，十二烷基苯磺酸（DBSA）为有机模板剂，成功合成了ZnO-SnO 2胶体纳米粒子。利用X射线衍射（XRD）和透射电子显微镜（TEM）对ZnO-SnO 2产物的组装纳米结构进行了研究。结果表明，ZnO-SnO 2胶体纳米粒子呈盘状多环纳米结构。这种有趣的结构主要是由ZnO-SnO_2混合物的韧性决定的。已经提出了基于前体和模板之间的静电相互作用的机制来说明所得的纳米颗粒结构。
ZnO–SnO2colloidal nanoparticles have been successfully synthesized by using the composite of ZnCl2and Sn(OC4H9)4as inorganic precursor and dodecylbenzenesulfonic acid (DBSA) as an organic template. The assembled nanostructures of ZnO–SnO2products have been carefully investigated by powder X-ray diffraction (XRD) and transmission electron microscopy (TEM). It is found that ZnO–SnO2colloidal nanoparticles take a disk-like multiring nanostructure. This interesting structure is predominantly determined by the tenacity for ZnO–SnO2mixtures to stabilize lamellae. A mechanism based on electrostatic interactions between the precursor and template has been proposed to illustrate the resulting nanoparticle structure.
