The invention belongs to the technical field of metal oxide materials, and discloses a method for synthesizing cobalt hydroxide and cobalt hydroxide. The method for synthesizing comprises the following steps: stirring and heating ammonium citrate, introducing protective gas, adding cobalt salt, mixing The alkaline solution is reacted, pH is adjusted, and the cobalt hydroxide slurry is obtained; the cobalt hydroxide slurry is subjected to alkali leaching, the filter residue is collected by filtration, the filter residue is slurried, and then the detergent is added for washing and drying to obtain the cobalt hydroxide. In the present invention, ammonium citrate is used as the bottom liquid, cobalt liquid and mixed alkali liquid are added, and the cobalt hydroxide slurry is synthesized in one step under the protective atmosphere. Adding a dispersant to the cobalt liquid can reduce the generation of flocs and improve the hydrogenation rate. Active specific surface area of cobalt. |
