Nanoscale FeS and FeS mixed phases were synthesized by one-pot decomposition of (-anil--piperldtc)Fe1 as FeS#1), (-piperldtc)Fe2 as FeS#2) and (-anildtc)Fe3 as FeS#3) complexes as precursors, with the help of tri-n-octylphosphine oxide (TOPO) coordinating solvent. Their morphology, stability, size, optical and structural characteristics were observed using various material characterization instruments. In comparison to the FeS#2 nano-flower shape, FeS#1 and FeS#3 have a uniform nano-rod shape. A one-step decomposition pattern was obtained from the thermal gravimetric analysis (TGA) results with 3% final mass residual. The high-resolution transmission electron microscopy (HRTEM) image reveals an aggregation and size diameter of around 14.47-30.25 nm for the three samples. The optical response between 3.8 and 4.2 eV from the three samples shows that they are inconsiderable materials for solar cells application. The diffraction peaks for the three samples matched well with the FeS/FeS. These nanoscale materials can be used in a variety of applications, including lithium-ion batteries, biosensors, hydrogen evolution, and multifunctional nanocomposite materials.
通过一锅法分解（-苯胺基-哌啶二硫代甲酸盐）铁1（FeS#1）、（-哌啶二硫代甲酸盐）铁2（FeS#2）和（-苯胺二硫代甲酸盐）铁3（FeS#3）配合物作为前驱体，并借助三正辛基氧化膦（TOPO）配位溶剂，合成了纳米级FeS和FeS混合相。使用各种材料表征仪器观察了它们的形态、稳定性、尺寸、光学和结构特征。与FeS#2的纳米花形状相比，FeS#1和FeS#3具有均匀的纳米棒形状。热重分析（TGA）结果显示出一步分解模式，最终质量残留为3%。高分辨率透射电子显微镜（HRTEM）图像显示，这三个样品的团聚体尺寸直径约为14.47 - 30.25纳米。这三个样品在3.8至4.2电子伏特之间的光学响应表明，它们对于太阳能电池应用来说是不太理想的材料。这三个样品的衍射峰与FeS/FeS匹配良好。这些纳米级材料可用于多种应用，包括锂离子电池、生物传感器、析氢以及多功能纳米复合材料。
