Abstract:
A facile and environmentally friendly hydrothermal approach has been employed to synthesize size‐controllable quasi‐cubic α‐Fe 2 O 3 nanocrystals by using an aqueous solution of FeCl 3 without any alkaline materials and stabilizing agent. The as‐prepared products were carefully characterized and the growth mechanism is also discussed. This hydrothermal synthesis of such quasi‐cubic structures implies a simple and low‐cost route to prepare monodisperse nanomaterials on a large scale. The size‐controllable synthesis of α‐Fe 2 O 3 is the first achieved successfully from 80 nm to 2 μm with constant structures. The synthesized α‐Fe 2 O 3 materials have different optical properties and stabilities in water, which are caused by the change of their band‐gap energy and specific surface areas. Finally, the dielectric properties of synthesized α‐Fe 2 O 3 cubes were also investigated, and the differences caused by the particle sizes are discussed.
