Title:
CARBON POLYMER DOT COMPOSITE BISMUTH OXYCARBONATE NANOSHEET MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/088433
Kind Code:
A1
Abstract:
A carbon polymer dot composite bismuth oxycarbonate nanosheet material, and a preparation method therefor and the use thereof, which belong to the technical field of nanomaterials. The preparation method comprises the following steps: sequentially dissolving CTAB and HMT in an ethanol solution, then adding BiCl3, Na2CO3 and carbon polymer dots, stirring the mixture, then subjecting the mixture to an in-situ composite reaction, and then washing and drying same to obtain a carbon polymer dot composite bismuth oxycarbonate nanosheet material. Further provided are the carbon polymer dot composite bismuth oxycarbonate nanosheet material prepared by using the preparation method, and the use of same in the photocatalytic degradation of organic dyes, antibiotics or phenolic pollutants in water. The material improves the spectral response range of a photocatalyst, achieves the efficient visible light catalytic oxidation activity, has the advantages of a high photocatalytic efficiency, a simple and rapid method, and economy and environmental protection, etc., and can also maintain a good photocatalytic activity in a seawater environment.
