Title:
MODIFIED CNF MEMBRANE CAPABLE OF CATALYTICALLY DEGRADING 4-NITROPHENOL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/068449
Kind Code:
A1
Abstract:
The present invention relates to the technical field of cellulose nanofiber membrane catalysts, and relates in particular to a modified CNF membrane capable of catalytically degrading 4-nitrophenol, a preparation method therefor and an application thereof. The modified CNF membrane comprises: cellulose nanofibers and nano CuO particles, the nano CuO particles being grown in situ on the cellulose nanofibers, and the surfaces of the cellulose nanofibers being grafted with amine groups. The modified CNF membrane of the present invention has excellent catalytic degradation capabilities for degradable 4-nitrophenol, and may efficiently catalytically degrade 4-nitrophenol within a short period of time.
