Abstract

The invention relates to a preparation method of a nickel-carbon-based material. The preparation method of the nickel-carbon-based material is as follows: respectively dispersing soluble nickel salt and dibasic organic acid in an amide organic solvent to prepare a mother liquor with a certain concentration. Under stirring conditions, press Ni 2+ / ‑COOH (organic acid radical) is in a molar ratio of 20:1 to 1:10, and the above mother liquors are mixed. After stirring for 0.5h to 10h, transfer to a pressure vessel, and stand at a temperature of 200°C to 300°C for 12h to 72h. The nickel-carbon-based material was obtained after the precipitate was separated, washed with alcohol, and dried in vacuum. The material has high thermal stability, and the specific surface is as high as 234m 2 / g, which is expected to be applied in the fields of electrodes, magnetism, catalysis and other materials.

Description

technical field [0001] The invention belongs to the technical field of preparation of carbon-based materials, and in particular relates to the preparation of a nickel-carbon-based material. Background technique [0002] Nickel is a transition metal element with a high content in the earth's crust, and it is a commonly used catalytic and magnetic material. Since Normann realized the catalytic hydrogenation of nickel-based catalysts in 1902, the research on nickel-based materials has attracted the attention of researchers. Especially in recent years, the research on nickel-based materials, including their preparation methods and application fields, has achieved remarkable development, and new nickel-based materials have been developed, which are widely used in hydrogenation of carbonyl compounds, magnetic materials, etc. [0003] Patent CN105289614A discloses the preparation of a nickel-carbon catalyst for hydrogen production. Ni-MOF material is prepared first, and then nicke...
