Preparation method of cobalt-nickel double metal hydroxide nano composite

The present invention provides a process of hydrolysis prepared by cobalt - nickel-double hydroxide nanocomposite method belongs to the technical field of the preparation of nanomaterials. The present invention is carried out at room temperature without heating and temperature control means, distilled water as the hydrolysis solvent, using sodium borohydride to provide an alkaline environment for the reaction, the simple synthesis steps, high yield, resulting in a cobalt - nickel-metal hydroxide bis based nanocomposite material as graphene structure; the present method of preparation is simple, energy saving, suitable for industrial production, to obtain cobalt - Nickel bis metal hydroxide nanocomposite has a good effect on the catalytic hydrogenation of p-nitrophenol.
