Transition metal chalcogenides have attracted much attention owing to their unique properties and various potential applications. However, it is rather challenging to explore a facile and versatile strategy to synthesis of Fe3S4 nanosheets. In this paper, we have developed an easy and controllable method to prepare large-scale Fe3S4 nanosheets, which have unique morphology, large specific surface area, and ferromagnetic behavior. The growth process of Fe3S4 nanosheets has been investigated based on the results of time-dependent experiments. When they were employed as anode materials for lithium-ion batteries, the Fe3S4 nanosheets can deliver stably reversible capacity of 548 mA h g(-1) after 120 cycles at a current density of 0.2 A g(-1) and superior rate performance.
