| titleOfInvention | Preparation method and application of CoO/NiOOH composite material |
| abstract | The invention relates to a preparation method of a CoO/NiOOH composite material, which comprises the following steps: s1: dissolving soluble cobalt salt in methanol to obtain a methanol solution of the cobalt salt; dissolving 2-methylimidazole in methanol to obtain a methanol solution of 2-methylimidazole; mixing the methanol solution of the cobalt salt and the methanol solution of the 2-methylimidazole under the condition of stirring to obtain a uniform solution; s2: placing the uniform solution in a reaction kettle for hydrothermal reaction, and calcining precipitates obtained by the hydrothermal reaction under the conditions of washing, drying and protective atmosphere to obtain CoO; s3: adding the CoO obtained in the step S2 into water, and adding nickel sulfate and K under the stirring condition 2 S 2 O 8 And (3) forming a uniform suspension, then dropwise adding ammonia water into the uniform suspension to adjust the pH value of the solution to 9.5-10.5, reacting under the conditions of heating and stirring, and washing and drying the precipitate after reaction to obtain the CoO/NiOOH composite material. Compared with the prior art, the invention has the advantages of environmental protection, simple preparation method, convenience for large-scale production and the like. |
