通过溶剂热法在相对较低的温度下大量合成一维二硫化铁（FeS2）纳米结构。研究发现，铁源阴离子、温度和溶剂中前驱体的摩尔浓度对控制 FeS2 纳米结构的形貌起着重要作用。通过 SEM 和 TEM 图像研究了这些实验参数的影响。通过 XRD、HRTEM 和 SAED 图谱研究了 FeS2 纳米形态的晶体结构，并鉴定为立方黄铁矿。 (C) 2004 Elsevier B.V. 保留所有权利。
One-dimensional nanostructures of iron di-sulfide (FeS2) were synthesized in large quantities by solvothermal process at relatively low temperature. It is found that the anions of the iron source, temperature and the molar concentrations of the precursors in the solvent play an important role in controlling the morphology of the FeS2 nanostructures. The effects of these experimental parameters have been investigated by the SEM and TEM images. The crystal structures of the FeS2 nanoforms were studied by the XRD, HRTEM and SAED patterns and identified as cubic iron pyrite. (C) 2004 Elsevier B.V. All rights reserved.
