| titleOfInvention | Preparation method of superfine beta-FeOOH nanorod self-assembled hollow microsphere under urea action |
| abstract | A method for preparing superfine beta-FeOOH nano-rod self-assembled hollow microspheres under the action of urea comprises the steps of adding a certain amount of soluble salts ferric trichloride, sodium chloride and urea into absolute ethyl alcohol and deionized water to obtain a suspension A; pouring the suspension A into a homogeneous hydrothermal reaction kettle, sealing the reaction kettle, putting the reaction kettle into a homogeneous hydrothermal reaction instrument for hydrothermal reaction, and naturally cooling to room temperature to obtain a product B; washing the product B with water and alcohol respectively, and dispersing the washed product in water to obtain a product C; and (4) freeze-drying the product C to obtain the superfine beta-FeOOH nanorod self-assembled hollow microspheres under the action of urea. The method adopts a homogeneous hydrothermal method, is simple, short in time consumption, low in cost and easy to implement; the superfine beta-FeOOH nanorod self-assembled hollow microsphere has larger specific surface area under the action of urea, can provide more electrochemical reaction active sites, and improves the reaction activity of the beta-FeOOH conversion reaction. |
