摘要

We have studied the growth of silica-sheathed 3C-Fe₇S ₈ products on silicon substrates with FeCl₂ and sulfur precursors at the temperature region of 600-800°C. On the basis of the crystal structure of Fe₇S₈, we have proposed a model including the kinetic competition of the adsorption of silica species on Fe2-Fe3-Fe4 units at the 4Fe layer and on the Fe2-Fe3-Fe4-Fe5 units parallel to the c-axis. Using this model, we have not only explained all the experimental phenomena but also especially prepared Fe₇S₈ nanowires at 650°C by introducing water into the reaction system.
