Hollow metal chalcogenides have attracted increasing attention in recent years owing to their widespread applications. However, to the best of our knowledge, the effective synthesis of a uniform Fe3S4 hollow nanostructure for fundamental research and practical application has not been reported to date. In this paper, a facile method for preparing nanostructured Fe3S4 with controlled hollow spheres was developed. The as-prepared Fe3S4 shows ferromagnetic characteristic and porous nature. Their Li ion storage and water treatment performances are further tested. Such mesoporous hollow spheres exhibit a highly reversible capacity of 750 mA h g(-1) over 100 cycles at a current density of 0.2 A g(-1). In addition, when used as an adsorbent, the Fe3S4 exhibited high adsorption capability and the adsorption isotherms are subject to the Freundlich equation. This work not only presents a facile strategy for the synthesis of novel Fe3S4 hollow spheres but also supplies a promising advanced material for lithium-ion batteries and water treatment.
