Preparation method of thorium dioxide nano material
The invention belongs to the technical field of nano materials, and relates to a preparation method of a thorium dioxide nano material. The preparation method comprises the following steps: uniformlymixing 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, drying and grinding to obtain the thorium dioxide nano material. With application of 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 large scale.
本发明属于纳米材料技术领域，涉及一种二氧化钍纳米材料的制备方法。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pH7.5‑8.5，烘干研磨，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。
