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.
通过微波辅助法在室温下于水溶液中制备了三元NaFeS₂纳米颗粒。产物呈纤维状，直径小于10纳米，通过X射线衍射（XRD）图谱、透射电子显微镜（TEM）图像、选区电子衍射（SAED）图谱和X射线光电子能谱（XPS）图谱对其进行了表征。结果表明，纤维状三元纳米颗粒的组成中Na:Fe:S的原子比为1:1.1:1.9。探讨了纤维状NaFeS₂纳米颗粒的形成机制。
