High saturation magnetization of γ-Fe2O3 nano-particles by a facile one-step synthesis approach

We have demonstrated the synthesis of γ-Fe 2 O 3 nano-particles through a facile and novel calcination process in the air. There is no p H regulation, gas atmosphere, additive, centrifugation or other complicated procedures during the preparing process. A detailed formation process of the nano-parti...

Description
Summary:We have demonstrated the synthesis of γ-Fe 2 O 3 nano-particles through a facile and novel calcination process in the air. There is no p H regulation, gas atmosphere, additive, centrifugation or other complicated procedures during the preparing process. A detailed formation process of the nano-particles is proposed and DMF as a polar solvent may slower the reaction process of calcination. The structures, morphologies and magnetic properties of γ-Fe 2 O 3 nano-particles were investigated systematically and the pure γ-Fe 2 O 3 nano-particles obtained at 200 °C display uniform morphology good magnetic property. The saturation magnetization of obtained pure γ-Fe 2 O 3 is about 74 emu/g, which is comparable with bulk material (76 emu/g) and larger than other results. In addition, the photocatalytic activity for degradation of methylene blue is also studied, which shows proper photocatalytic activity.
