以Zn(Ac)2和Na2S为原料、EDTA为稳定剂、OA为结构导向模板,采用水热合成方法成功地制备了具有层状介观结构的ZnS纳米纤维;通过XRD, TEM, SEM, N2-吸附/脱附以及紫外-可见漫反射等手段对所得的产物进了表征,并初步探讨了其形成机理.

Novel lamellar mesostructured ZnS nanofibers with uniform diameter in about 20~40 nm and length up to several micrometers have been facilely synthesized via hydrothermal reaction of Zn(Ac)2 and Na2S using neutral octylamine (OA) as structure-directing agent and ethylene diamine tetraacetic acid (EDTA) as stabilizer. The as-synthesized products were characterized via XRD, TEM, SEM, N2 adsorption isotherms and the UV-visible absorption spectra. A possible formation mechanism for the mesostructured nanofibers was also discussed.

Key words: ZnS, nanofiber, mesostructure, morphology
