Fe(OH)2and the as-prepared Fe3O4. (a) TEM images of Fe(OH)2and (b) low-magnification SEM images of the as-prepared Fe3O4obtained in pure aqueous solution. It can be seen that the product is a mixture of polygonal particles and fiber-like particles. (c) SEM and (d) TEM images and (e) the SAED pattern of Fe(OH)2 obtained in the EG-H2O mixture.
