Polyhedral magnetite nanocrystals with multiple facets: Facile synthesis, structural modelling, magnetic properties and application for high capacity lithium storage

Journal Article


Abstract


  • Polyhedral magnetite nanocrystals

    with multiple facets were synthesised

    by a low temperature hydrothermal

    method. Atomistic simulation

    and calculations on surface attachment

    energy successfully predicted the polyhedral

    structure of magnetite nanocrystals

    with multiple facets. X-ray diffraction,

    field emission scanning electron

    microscopy, and high resolution transmission

    microscopy confirmed the crystal

    structure of magnetite, which is consistent

    with the theoretical modelling.

    The magnetic property measurements

    show the superspin glass state of the

    polyhedral nanocrystals, which could

    originate from the nanometer size of

    individual single crystals. When applied

    as an anode material in lithium ion

    cells, magnetite nanocrystals demonstrated

    an outstanding electrochemical

    performance with a high lithium storage

    capacity, a satisfactory cyclability,

    and an excellent high rate capacity.
