Abstract

The invention discloses a sulfaquinoxaline cobalt-nickel nano composite material and a preparation method thereof. According to the invention, a certain amount of a metal salt solution is added to a sulfaquinoxaline-containing organic ligand, and the obtained product is stirred at a certain temperature. After the treatments of microwave reaction, ultrasonic dispersion, centrifugal separation, washing, and drying, a corresponding metal-ligand nano composite material is obtained. The method is simple in preparation process, low in cost and suitable for mass production. Through selecting different solvents, controlling the amounts of reactants, the reaction time and the reaction temperature, the particle size of sulfaquinoxaline cobalt-nickel nano composite material and the dispersibility thereof are effectively controlled. The prepared sulfaquinoxaline cobalt-nickel nano composite material is a functionalized composite material containing cobalt and nickel, and is stable in performance. The material can be used for catalyzing the C-C bond coupling reaction, and is high in catalytic efficiency. Therefore, the sulfaquinoxaline cobalt-nickel nano composite material has a wide application prospect in the catalysis field.

Description

technical field

[0001] The invention belongs to the catalytic application field of metal-organic nanocomposite materials, and in particular relates to a sulfaquinoxaline cobalt-nickel nanocomposite material for catalytic coupling reaction and a preparation method thereof. Background technique

[0002] Nanomaterials refer to materials that have at least one dimension in the three-dimensional space in the nanoscale range or are composed of them as basic units. Nanomaterials have aroused people's interest because of their special physical and chemical properties, and have become "stars" in material science. On the other hand, nanoparticles have high surface activity and excellent catalytic performance.

[0003] At present, most of the catalysts for carbon-carbon coupling reaction are palladium nano-catalysts, noble metal nano-catalysts and nano-molecular sieve catalysts. In recent years, the research on nano-nickel catalysts has been continuously deepened, and the applicatio...
