The invention discloses a preparation method of Co(OH) 2 @CoMoO 4 composite nanosheets, including: S1, processing nickel foam; S2, growing CoMoO 4 nanosheets on nickel foam: adding nickel foam to divalent cobalt salt and six valent molybdate mixed solution, after hydrothermal reaction, washed and dried; S3, preparation of Co(OH) 2 @CoMoO 4 nanosheets: CoMoO 4 nanosheets were put into 2-methylimidazole solution, divalent The cobalt salt solution was quickly poured into the 2‑methylimidazole solution containing CoMoO4 nanosheets, stirred, sonicated, washed and dried. Compared with the prior art, the beneficial effect of the invention is that the preparation method is simple, the cost is low, and it can be used in large-scale production. Co(OH) 2 @CoMoO 4 nanosheets have high specific capacity and good charge storage ability, and can be used as electrode materials. |
