Title:
HETEROGENEOUS DUAL-CATALYTIC-CENTER CATALYST, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/078481
Kind Code:
A1
Abstract:
The present invention relates to the technical field of catalytic chemistry, and in particular to a dual-catalytic-center catalyst, a preparation method therefor and a use thereof, and a preparation method for dihydric alcohol. The catalyst comprises a porous carrier, and C3N4, a hydrogenation metal and a retro-aldol catalytic metal which are loaded on the porous carrier. The hydrogenation metal, the retro-aldol catalytic metal, and C3N4 form a cluster. The hydrogenation metal, the retro-aldol catalytic metal, and N sites are coordinated and loaded on the porous carrier, and form a cluster with C3N4 to effectively stabilize the metal active sites. The catalyst is used for preparing dihydric alcohol from a polyhydroxy compound; the raw material conversion rate and the product dihydric alcohol selectivity are high; the cycle stability of the catalyst is high, and no catalyst deactivation is observed after four times of recycling.
