Title:
N-DOPED BISMUTH OXYCARBONATE COMPOSITE GRAPHITE-PHASE CARBON NITRIDE MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/088432
Kind Code:
A1
Abstract:
An N-doped bismuth oxycarbonate composite graphite-phase carbon nitride material, and a preparation method therefor and the use thereof, which belong to the technical field of photocatalytic materials for degrading wastewater pollutants. An N-doped bismuth oxycarbonate is synthesized by means of a hydrothermal method, and the N-doped bismuth oxycarbonate and graphite-phase carbon nitride are then condensed and refluxed by means of an electrostatic adsorption method to synthesize the N-doped bismuth oxycarbonate composite graphite-phase carbon nitride material. The N-doped bismuth oxycarbonate and the graphite-phase carbon nitride are effectively compounded, and the N-doped bismuth oxycarbonate and the graphite-phase carbon nitride are compounded to form an S-shaped heterojunction structure by means of the interaction between the N-doped bismuth oxycarbonate and the graphite-phase carbon nitride, such that the light absorption range can be widened, the light absorption intensity can be enhanced, the separation and transfer of photon-generated carriers can be promoted, and the photocatalytic degradation performance of organic dyes, antibiotics and phenolic pollutants in environmental water is further improved.
