Embodiment 1
[0029] 1.1 Dissolve 2.4g of ferric nitrate nonahydrate and 0.24g of aluminum trichloride in 18mL of water and mix well, then add 2mL of ammonia water and stir to obtain a uniform solution.
[0030] 1.2 Put the solution of 1.1 into a hydrothermal reaction kettle, seal it, and keep it warm at 180°C for 20 hours to obtain the final product, which is centrifuged and washed to obtain ferric oxide nanosheets.
[0031] 1.3 The electron micrograph of the ferric oxide nanosheet that the present embodiment obtains is as figure 1 As shown, it can be seen from the figure that the prepared product has a uniform size, a diameter of about 300 nm, and a thickness of about 20 nm. There is a through hole in the middle of the nanosheet, and the diameter of the through hole is 20-80 nm. . The XRD pattern of the product is as follows figure 2 As shown, it can be seen from the figure that the resulting product is hexagonal system ferric oxide.
Embodiment 2
[0033] 2.1 Dissolve 2.4g of ferric nitrate nonahydrate and 0.12g of aluminum trichloride in 19mL of water and mix well, then add 1mL of ammonia water and stir to obtain a uniform solution.
[0034] 2.2 Put the solution of 2.1 into a hydrothermal reaction kettle, seal it, and keep it warm at 120°C for 40 hours to obtain the final product, which is centrifuged and washed to obtain coin-like ferric oxide nanosheets.
[0035] 2.3 The ferric oxide nanosheets obtained in this example have a diameter of about 200 nm, a thickness of about 30 nm, and a through hole diameter of about 50 nm.
Embodiment 3
[0037] 3.1 Dissolve 1.9g of anhydrous ferric trichloride and 0.38g of aluminum trichloride in 16mL of water and mix well, then add 3.0mL of ammonia water and stir to obtain a uniform solution.
[0038] 3.2 Put the solution of 3.1 into a hydrothermal reaction kettle, seal it, and keep it warm at 220°C for 35 hours to obtain the final product, which is centrifuged and washed to obtain copper coin-shaped ferric oxide nanosheets.
[0039] 3.3 The ferric oxide nanosheets obtained in this example have a diameter of about 600 nm, a thickness of about 30 nm, and a through hole diameter of about 80 nm.
