Title:
DEFECT-RICH COVALENT ORGANIC FRAMEWORK MATERIAL, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF IN PHOTOCATALYTIC HYDROGEN EVOLUTION
Document Type and Number:
WIPO Patent Application WO/2023/077285
Kind Code:
A1
Abstract:
Disclosed in the present invention are a defect-rich covalent organic framework material, a preparation method therefor, and an application thereof in photocatalytic hydrogen evolution. Specifically, the present invention prepares a series of defect-rich covalent organic framework materials by using unilateral aldehyde as a regulator and adjusting the amount of the unilateral aldehyde. The materials can decompose water under a photocatalytic condition to produce hydrogen, and have the characteristics of high efficiency and environment-friendly and mild reaction conditions. After a conversion reaction is completed, a catalyst is separated from the system and is used in a next round of reaction. After four times of recycling, the stability of the catalyst can still be maintained, and the catalytic activity of the catalyst is not significantly reduced.
