One-Step Synthesis of Fe₃S₄ Micro-Crystals and its Facile Transformation to Fe₇S₈ Micro-Crystals

Abstract:

A flask solvothermal method was firstly utilized to facile synthesize greigite Fe₃S₄ micro-crystals (MCs). By using iron nitrate, element sulfur as raw materials as well as oleylamine as the solvent, high yield of Fe₃S₄ MCs with hexahedron microstructure was obtained. In addition, it was found that it was easily to achieve transformation between Fe₃S₄ and Fe₇S₈ through changing reaction temperatures and iron-sulfur ratios. The several different morphologies of Fe₃S₄ MCs were obtained by using other sulfur sources. The synthetic approach demonstrated here could be of great potential for the controlled synthesis of other metal chalcogenides.
