Synthesis of Macroporous FeS₂ Nanotubes and their Electrochemical Properties

Abstract:

The particle size and morphology have a strong influence on the electrochemical performance of FeS₂ electrodes. In this paper, a simple one-pot solvothermal method is reported for the synthesis of macroporous pyrite nanotubes for the first time. The phase composition, morphology and structure of the as-obtained products were studied by the energy dispersive spectroscopy (EDS), scanning electron microscopy, (high-resolution) transmission electron microscopy, X-ray diffraction. The electrochemical properties of the FeS₂ samples were also investigated. The results demonstrated that the macroporous pyrite nanotubes delivered a higher initial discharge capacity of 925.2 mAh g^-1 and had good capacity retention.
