Problems solved by technology

In one-dimensional α-Fe 2 o 3 People have done some work on the preparation aspect: gas phase synthesis [Y.Y.Fu, R.M.Wang, J.Xu, J.Chen, Y.Yan, A.V.Narlikar and H.Zhang Chemical Physics Letters, 2003, 379, (3-4 ), 373-379. Yunyi Fu, Jing Chen and Han Zhang, Chemical Physics Letters, 2001, 350(5-6), 491-494.] template method [Feng Jiao, Bin Yue, Kake, Zhu, DongyuanZhao, Heyong He , Chemistry Letters, 2003, 32, (8), 770-771.], single crystal or polycrystalline substrate growth method [Lionel, Vayssieres, Niclas, Beermann, Sten-EricLindquist, Anders, Hagfeldt, Chemistry ofMaterials, 2001, 13 (2), 233-235.] Sol-gel method [Cairong Gong, Dairong Chen, Xiuling Jiao and Qilong Wang, J.Mater.Chem., 2004, 14(5), 905-907.]. The gas phase method usually requires Special equipment and high reaction temperature, the use of templates or substrates will complicate the operation steps, the cost will be high, and impurities will be introduced, making it difficult to achieve large-scale industrial production

Embodiment 1

[0019] Weigh 0.0005mol of ferrous sulfate and 0.001mol of anhydrous sodium acetate and add 20ml of water to dissolve, electromagnetically stir in the air for 20min, transfer to a 20ml stainless steel reaction kettle, conduct a hydrothermal reaction at 110°C for 8 hours, and then cool the completely reacted product to room temperature, and finally washed with deionized water and vacuum-dried to obtain the product α-FeOOH nanorods. The obtained α-FeOOH nanorods were calcined in a muffle furnace at 240 °C for 2 hours to obtain α-Fe 2 o 3 Nano stave.

Embodiment 2

[0021] Weigh 0.0005mol ferrous chloride and 0.001mol anhydrous sodium acetate, add 20ml water to dissolve, electromagnetically stir in the air for 5min, transfer to a 20ml stainless steel reaction kettle, react hydrothermally at 80°C for 5 hours, and then cool the completely reacted product to room temperature, and finally washed with deionized water and vacuum-dried to obtain the product α-FeOOH nanorods. The obtained α-FeOOH nanorods were calcined in a muffle furnace at 300 °C for 1.5 hours to obtain α-Fe 2 o 3 Nano stave.

Embodiment 3

[0023] Weigh 0.001mol of ferrous sulfate and 0.002mol of anhydrous potassium acetate and add 20ml of water to dissolve, electromagnetically stir in the air for 30min, transfer to a 20ml stainless steel reaction kettle, conduct a hydrothermal reaction at 60°C for 12 hours, then cool the completely reacted product to room temperature, and finally washed with deionized water and vacuum-dried to obtain α-FeOOH nanorods. The obtained α-FeOOH nanorods were calcined in a muffle furnace at 360 °C for 1.5 hours to obtain α-Fe 2 o 3 Nano stave.

Abstract

The production method of one-dimentional alpha-FeOOH and alpha-Fe2O3 nano material. Said method includes the following steps: a. adding soluble strong-base wear-acid salt in the soluble salt solution in which divalent iron is dissolved, stirring them to produce yellow precipitate; b. placing the above-mentioned material into a reactor, heating, after the reaction is completed, cooling to room temperature and c. washing and drying so as to obtain one-dimensional alpha-FeOOH nano material, then calcining said one-dimentional alpha-FeOOH nano material at 240-360 deg.C to obtain one-dimentional alpha-Fe2O3 nano material.
