中文摘要：

采用水热法以硫酸亚铁（FeSO4）、硫代硫酸钠（Na2S2O3）和硫粉（S）为反应物,在180℃下反应24h合成了二硫化亚铁（FeS2）纳米晶体.通过X射线衍射（XRD）、拉曼光谱（Raman）、场发射扫描电镜（FESEM）和紫外可见吸收光谱（UVvis）对所得产物进行分析表征.FESEM分析表明：FeS2纳米晶体为较薄的菱形片状结构,边长在640nm左右,厚度约为100nm.实验分析结果表明：采用此方法合成的FeS2纳米晶体具有相纯、几乎没有杂质等优点,而且该反应的用时相对较短,对实验条件和设备的要求也不高.同时还探究了实验可能的反应原理.

英文摘要：

FeS2 nanoflakes was synthesized through a hydrothermal method with FeSO 4 , Na2 S2 O3 and S as precursors reacting in 180 ℃ for 24 h.After that they were characterized by X-ray diffraction ( XRD), Ra-man, Field Emission Scanning Electron Microscopy ( FESEM ) and UV-visible absorption spectrum.FESEM analysis showed that the flakes were rhombus with about 640 nm in length and thickness of about 100 nm.The result showed that this method could help to synthesize high quality FeS2 nanoflakes with single crystal phase under simple experiment conditions.The possible reaction mechanism was discussed also.
