Abstract

The invention discloses a method for preparing a hollow spherical ferroferric oxide nano material, which comprises the following steps: dissolving ferric chloride hexahydrate in glycol or diethylene glycol and stirring the solution uniformly, wherein the dosage of the glycol or diethylene glycol is 1 to 4 milliliters of glycol or diethylene glycol per millimol of ferric chloride hexahydrate; dissolving anhydrous sodium acetate or sodium succinate or a mixture of anhydrous sodium acetate and sodium succinate in any ratio in solution prepared by the step 1 and stirring the mixed solution with ultrasonic waves to obtain uniform yellow brown sticky solution, wherein the mass ratio of the anhydrous sodium acetate or sodium succinate to the ferric chloride hexahydrate is 1:1 to 4:1; and transferring solution obtained by the step 2 to a liner of a water hydrothermal kettle, closing the kettle for reaction at 180 to 220 DEG C for 6 to 16 hours, naturally cooling the resulting product to room temperature, taking a sample out of the kettle and washing the sample with water and ethanol sequentially to obtain the hollow spherical ferroferric oxide nano material.

Description

technical field

[0001] The invention relates to a preparation method of a hollow spherical ferric oxide nanometer material. Background technique

[0002] As a kind of magnetic nanomaterial, ferroferric oxide has very important uses in many aspects, such as in catalysis, it can be used as a carrier of active substances, recycled, and the cost of catalysis can be reduced; in biotechnology, it can be used for the treatment of diseases. Track targeting, clinical diagnosis, hyperthermia, magnetic labeling, magnetic resonance imaging, etc. In addition, it can also be used in data storage, environmental pollution control, military and other fields. In view of the above reasons, ferric oxide has been extensively studied [see: (a) Ge, J.P.; Hu, Y.X.; Biasini, M.; Beyermann, W.P.; Yin, Y.D.Angew.Chem.Int.Ed.2007, 46, 4342.
