The invention relates to an aluminum hydroxide nanomaterial and a preparation method thereof, belonging to the field of preparation of IIIA group oxyhydroxide nanomaterials. The aluminum hydroxide nanomaterial is composed of aluminum hydroxide nanocones and nanoflowers self-assembled by the nanocones. The preparation method is as follows: adding anhydrous aluminum chloride to anhydrous ethanol, and using a magnetic stirrer to mix it uniformly; then adding oleic acid to the mixed solution of anhydrous aluminum chloride and anhydrous ethanol, and continuing to use a magnetic stirrer to mix it. Mix evenly; then pour the mixed solution into the reaction kettle, seal and keep it at 180-200°C for 24-48 hours; after the reaction, cool down to room temperature naturally, wash, dry and grind the product to obtain white aluminum hydroxide powder. The invention has simple operation method, easy control, good repeatability, high sample purity and good crystallinity. |
