Embodiment 1

[0026] A. Prepare egg white solvent: Take 2.5 mL of egg white separated from eggs in a beaker at room temperature, and add 10 mL of water while stirring. Let the egg whites dissolve in water for 1 h, then use a centrifuge to separate the undissolved white matter. Take the remaining solution as egg white solvent.

[0027] B. Preparation of two-dimensional Fe 3 o 4 Nanomaterials: Weigh 0.025g of ferric sulfate and add it to 12.5mL of egg white solvent, stir evenly to obtain an orange-yellow solution.

[0028] Dissolve 0.1 g of CTAB in 5 mL of absolute ethanol.

[0029] Slowly pour the orange-yellow solution into ethanol dissolved in CTAB, and stir for 15 minutes to obtain a yellow-white precipitated solution, then slowly add 5 mL of 50% hydrazine hydrate. After stirring for 15 minutes, the above-mentioned prepared reaction solution was transferred to a 30 mL polytetrafluoroethylene-lined stainless steel reaction kettle, and sealed. React in an oven at 120°C for 12 hours.

Embodiment 2

[0032] A. Prepare egg white solvent:

[0033] At room temperature, take 3 mL of the egg white separated from the egg in a beaker, and add 10 mL of water while stirring. Let the egg white dissolve in water for 12 hours, and then use a centrifuge to separate the undissolved white matter. Take the remaining solution as the reaction solvent.

[0034] B. Preparation of two-dimensional Fe 3 o 4 nanomaterials:

[0035] Weigh 0.015g of ferric sulfate and add it into the above-mentioned egg white solution, stir evenly to obtain an orange-yellow solution.

[0036] Take 0.08g CTAB and dissolve in 5mL of absolute ethanol.

[0037] Slowly pour the orange-yellow solution into ethanol dissolved in CTAB, and stir for 15 minutes to obtain a yellow-white precipitated solution, then slowly add 5 mL of 80% hydrazine hydrate. After stirring for 15 minutes, the above-mentioned prepared reaction solution was transferred to a 30 mL polytetrafluoroethylene-lined stainless steel reaction kettle, ...

Embodiment 3

[0040] A. Prepare egg white solvent:

[0041] At room temperature, take 3 mL of the egg white separated from the egg in a beaker, and add 10 mL of water while stirring. Let the egg whites dissolve in water for 1 h, then use a centrifuge to separate the undissolved white matter. Take the remaining solution as the reaction solvent.

[0042] B. Preparation of two-dimensional Fe 3 o 4 nanomaterials:

[0043] Weigh 0.015g of ferric sulfate and add it into the above-mentioned egg white solution, stir evenly to obtain an orange-yellow solution.

[0044] Dissolve 0.16 g of CTAB in 5 mL of absolute ethanol.

[0045] Slowly pour the orange-yellow solution into ethanol dissolved in CTAB, and stir for 15 minutes to obtain a yellow-white precipitated solution, then slowly add 5 mL of urea solution (0.04 g of urea dissolved in 5 mL of water). After stirring for 15 minutes, the above-mentioned prepared reaction solution was transferred to a 30 mL polytetrafluoroethylene-lined stainless...

Abstract

The invention discloses a method for preparing a two-dimensional Fe3O4 nano material. The method comprises the following steps of A, preparing an egg white solvent; B, preparing the two-dimensional Fe3O4 nano material; and C, washing. Compared with the prior art, the method has the advantages that the synthetic method of the Fe3O4 nano material is simple and novel, can be accomplished by one step, is easily operated and high in repeatability; the two-dimensional profile of the material can be controlled under the condition that egg white is used; the size in the same dimension can be controlled; and the method can be widely used for preparing other two-dimensional metallic oxides. Besides, products prepared by the method have the characteristics of high purity, uniform size distribution and the like.

Description

Technical field: [0001] The invention belongs to the technical field of preparation methods of magnetic metal oxide nanomaterials, and provides a simple and novel method for preparing two-dimensional Fe 3 o 4 methods for nanomaterials. technical background: [0002] From the development of modern biotechnology, it is not difficult to find that many biological systems themselves are some perfect nano-machines. In fact, the biotechnological approach has become one of the approaches to nanotechnology. It can be combined with various disciplines to promote the development of various disciplines, and can also achieve its own perfection in the development and progress of other disciplines. In nature, there are many organisms that can synthesize inorganic materials with specific functions by themselves, such as magnetotactic bacteria, fish, molluscs, sea urchins, sponges, diatoms, etc., and the in-depth understanding of the fine structure of life itself is helpful for cell bett...
