In this article, a facile L-cysteine-assisted solvothermal method is described, which is about the larges-scale synthesis of Fe(0.985)S novel nanostructures in a mixed solution composed of ethylenediamine (EN) and distilled water. By varying process parameters, such as the molar ratio of Fe(3 )-to-L-Cysteine (reactants), the volume ratio of water to ethylenediamine, and the reaction temperature, different kinds of architectural structures can be controllably synthesized in large quantities. At the same time, a reasonable mechanism for the growth of iron sulfide structures has been proposed. The as-prepared iron sulfide products were characterized using diverse techniques including X-ray powder diffraction (XRD), fielde-mission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution TEM, superconducting quantum interface device (SQUID) magnetometer (Quantum Design MPMS XL).
