Abstract

The invention discloses a hydroxyl nickel chloride nano material and a preparation method thereof, and belongs to the field of preparation of VIII group hydroxyl chloride nano materials. The hydroxyl nickel chloride nano material is a compound NiOHCl formed by nickel, hydroxyl and chlorine according to the stoichiometric number ratio of 1: 1: 1, the hydroxyl nickel chloride nano material has a nanosheet shape, and the nanosheet has a straight and regular surface. The preparation method comprises the following steps: taking nickel chloride hexahydrate crystalline powder and nickel hydroxide powder as raw materials, firstly, fully mixing and grinding the two raw materials for 30-60 minutes, then sealing and heating for 5-7 hours at the temperature of 130-170 DEG C, cooling to room temperature after the reaction is finished, and continuously grinding the product for 10-30 minutes to obtain the hydroxyl nickel chloride nano material. The method overcomes the defects in the previous preparation process, and is simple, low in cost and easy to control.

Description

technical field [0001] The invention belongs to the field of preparation of group VIII hydroxychloride nanometer materials, and in particular relates to a simple, novel and efficient method for preparing nickel hydroxychloride nanomaterials. Background technique [0002] Finding efficient and clean new energy sources and energy storage technologies has always been a research topic that has attracted much attention. Nickel hydroxide and nickel oxide are the focus of attention and research in the field of new energy materials in the world. They have higher specific capacitance, power density and energy density. As one of the important precursors for the synthesis of nickel hydroxide and nickel oxide, nickel oxychloride is of great practical significance. [0003] Nickel hydroxychloride is a kind of two-dimensional layered nanomaterials. Since the discovery of graphene, other novel two-dimensional layered materials have been a hot topic in the field of materials research. So...
