Preparation method of thorium dioxide nano material
The invention discloses a preparation method of a thorium dioxide nano material, and belongs to the technical field of nano materials. The preparation method comprises the following steps: uniformly mixing a thorium nitrate solution and a sodium hydroxide solution, adding the mixture into a reaction kettle for hydrothermal reaction, cooling the reaction product to room temperature, washing the reaction product with water until the pH value is 7.5-8.5, and drying and grinding the reaction product to obtain the thorium dioxide nano material. By utilizing the preparation method of the thorium dioxide nano material, ThO2 ceramic nano powder with controllable morphology, light agglomeration, uniform particle size, high specific surface area and good catalytic activity can be prepared on a largescale.
本发明公开了一种二氧化钍纳米材料的制备方法，属于纳米材料技术领域。所述的制备方法是将硝酸钍溶液与氢氧化钠溶液混合均匀，加入反应釜中水热反应，反应产物冷却到室温后水洗涤至pH为7.5‑8.5，烘干研磨，即制得二氧化钍纳米材料。利用本发明的二氧化钍纳米材料的制备方法，能够大规模制备形貌可控、团聚较轻、粒径均匀、比表面积较高、催化活性好的ThO陶瓷纳米粉体。
