Document Type and Number:
WIPO Patent Application WO/2023/142671
Kind Code:
A1
Abstract:
Disclosed in the present application are a Cu-Al-Ni-Co-based catalyst, and a preparation method therefor and the use thereof. The composition of the Cu-Al-Ni-Co-based catalyst of the present application comprises CuO, Al2O3, Co3O4 and NiO. The preparation method for the catalyst comprises the following steps: dissolving copper and aluminum slag, which is generated during a lithium ion battery recovery process, in an acid, then adding an alkali for a co-precipitation reaction, separating out obtained precipitates, and then roasting same to obtain a Cu-Al-Ni-Co-based catalyst. The catalyst has abundant alkaline sites and active sites, has a simple and environmentally friendly preparation, has good catalytic activity and stability, can further realize resource cyclic regeneration, value addition and comprehensive utilization of waste battery materials and carbon dioxide, and is suitable for practical popularization and use.
