| 摘 要： | 以NiCl2·6H2O和硫脲为前驱液，在350℃的玻璃衬底上，通过超声喷雾热解技术与软模板相结合，成功地制备了产率较高的二硫化镍大尺度纳米线．利用X射线衍射仪（XRD）、透射电子显微镜（TEM）、偏光显微镜分别对产物的物相和形貌进行了表征．结果表明：所制备的NiS2纳米线沿（200）晶面具有明显的取向生长，长径比约为25：1，并对其生长机理做了初步的探讨．

| Abstract: | Large-scale nanowires of NiS2were synthesized using NiCl2 -6H2O and thiourea （CS（ NH2 ）2 ） as reactant by an ultrasonic spray pyrolysis technique combining with soft-template on glass substrate at 350℃. The prepared samples were characterized by using XRD, TEM and optical microscope. The results show that these large-scale nanowires were NiS2 nanowires with（200）preferential growth and diameter and length ratio of 25： 1. Its growth mechanism was preliminarily discussed as well. |
