| titleOfInvention | Preparation method and application of high-stability core-shell structure bimetallic copper-based catalyst |
| abstract | The invention provides a preparation method of a high-stability core-shell structure bimetallic copper-based catalyst, which comprises the steps of carrying out coprecipitation reaction to obtain a metal silicon composite oxide, then carrying out coprecipitation reaction to obtain a core-shell structure bimetallic composite oxide, filtering, washing with water, adding n-butyl alcohol, evaporating, drying and roasting to obtain the core-shell structure bimetallic copper-based catalyst. According to the invention, the metal silicon composite oxide is used as a skeleton structure substrate, the CuSiO composite oxide is coated on the outer side of the skeleton structure substrate to form the core-shell structure bimetal composite oxide, and the spontaneous movement of Cu atoms is hindered through the strong interaction and isolation action of the internal metal atoms and the external copper atoms and the embedding effect that the Cu atoms are highly dispersed in the skeleton structure CuSiO composite oxide, so that the stability and the service life of the copper catalyst are effectively improved, and the copper catalyst has high catalytic activity and specific surface area. |
