The Fe3O4 nanoparticles and nanoplates prepared under different conditions. (a) TEM and (b) SEM images of the as-prepared Fe3O4 nanoparticle (EG/H2O = 0:1). (c) TEM and (d) SEM images of Fe3O4 nanoplates prepared under the condition of EG/H2O = 3:1. The diameter of the nanoplates is about 150 to 200 nm, and the thickness of the nanoplate is about 10 nm. (e) TEM and (f) SEM images of the Fe3O4 nanoplates prepared under the condition of EG/H2O = 5:1. The diameter is about 80 to 10 nm, and the thickness is about 5 nm.
