Two different forms of nano-scale Fe2O3 were prepared by hydrothermal method using Fe(NO3)3•9H2O as the starting material, ethylenediamine and ethylene glycol methyl ether as surfactants. The structure, surface morphology and composition of nano-scale Fe2O3 samples were analyzed by XRD and SEM/EDS. The results show that the sample has two forms, one nano-Fe2O3 form is rod-shaped, and the rod-like structure is hexagonal columnar, the particles are closely arranged in disorder; the other nano-Fe2O3 is spherical, and there are agglomerates between the particles. Cluster phenomenon. The formation mechanism of the nano-oxidized iron was analyzed.
