摘　　要：常温下用微波辅助法制得了直径小于10nm的纤维状NaFeS2 三元化合物纳米粒子,并用X射线粉末衍射、透射电子显微镜、选区电子衍射和X射线光电子能谱对纳米微粒进行了表征。XPS能谱分析表明:产物中含有Na ,Fe,S三种元素,其比值为Na∶Fe∶S =1∶1 1∶1 9。探讨了纤维状NaFeS2 纳米粒子的形成机理。Ternary NaFeS2 nanoparticles were obtained in aqueous solution at room temperature via microwave- assisted route. The products were fibre-like with the diameter less than 10 nm, which were characterized with X-ray diffraction (XRD) pattern, transmission electron microscope (TEM) image, selected area electron diffraction (SAED) pattern and X-ray photoelectron spectroscope (XPS) pattern. The results indicated that the composition of fibre-like ternary nanoparticles are with atomic ratio of Na: Fe: S= 1: 1. 1: 1. 9. The mechanism for the formation of fibre-like NaFeS2 nanoparticles is discussed.
