Abstract

Aggregated α-Fe₂O₃ nanoplates have been successfully synthesized under ionothermal conditions through the self-assembly of nanoplatelets in a side-to-side manner. During the formation process of aggregated α-Fe₂O₃ nanoplates, pure ionic liquid media is essential for the assembly and coalescence of small nanoplatelets into final nanoplates. Moreover, the magnetic properties of the aggregated α-Fe₂O₃ nanoplates are strongly correlated to their unique structural characteristics.
