| Abstract: The α-Fe2O3 hollow spheres have been synthesized through the random aggregation of β-FeOOH nanorods in the C2H5OH/H2O system. The phase transformation and the morphologies of the α-Fe2O3 hollow structure were investigated with XRD， SEM， TEM and selected area electron diffraction (SAED). These studies indicate that the second step is a dissolution-recrystallization process. Furthermore， the formation mechanism of the hollow spheres has been discussed. It is found that the presence of H2O in the reaction system is essential to the final formation of the hollow spheres. |
