Title:
MONATOMICALLY DISPERSED PALLADIUM-BASED CATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/257025
Kind Code:
A1
Abstract:
The present application discloses a monatomically dispersed palladium-based catalyst, a preparation method therefor and an application thereof. The monatomically dispersed palladium-based catalyst comprises a main catalytic active component and a carrier; the main catalytic active component is a palladium element; the carrier is activated carbon having a surface to which a sulfur-containing functional group is linked; the palladium element is monatomically dispersed in the palladium-based catalyst in the form of a mononuclear complex, and the mononuclear complex is anchored to the surface of the activated carbon by means of the sulfur-containing functional group. Because the noble metal Pd in the catalyst provided by the present invention is monatomically dispersed, the prepared catalyst has a very high utilization rate of metal atoms, can be used for preparing a but(ene)dioic acid diester, and has good catalytic activity and stability.
