Title:
POLYCARBAZOLE-SUPPORTED NANO-PALLADIUM MATERIAL, PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/097894
Kind Code:
A1
Abstract:
The invention relates to a polycarbazole-supported nano-palladium material, a preparation method, and an application thereof. Specifically, the prepared palladium nanoparticles have an average particle size distribution of about 4.2 nm and are uniformly dispersed on the base polycarbazole material, are capable of catalyzing the participation of aryl bromide and aryl chloride in a Suzuki reaction under the conditions of illumination and a water phase, and have high conversion efficiency, a broad scope of application, and mild and environmentally-friendly reaction conditions. After the conversion reaction is complete, a substrate is separated from the reaction system, and the catalytic system can proceed to the next round of reaction. Stability can be maintained even after three cycles, and catalytic activity does not significantly decrease.
