Problems solved by technology

However, the current graphene oxide-based photocatalytic materials have low dispersion and are easy to agglomerate, which hinders the transfer rate of photogenerated carriers on the surface of graphene oxide and greatly inhibits its photocatalytic activity.
In addition, the problem of solid-liquid separation seriously hinders the practical application of graphene oxide-based photocatalytic materials.

Abstract

The invention relates to a boron nitride quantum dot modified nano annular magnetic graphene oxide photocatalytic material and a preparation method and application thereof, the boron nitride quantum dot modified nano-ring-shaped magnetic graphene oxide photocatalytic material comprises a magnetic ferroferric oxide nano-ring, and the surface of the magnetic ferroferric oxide nano-ring is coated with graphene oxide. Boron nitride quantum dots are grafted on the graphene oxide; the preparation method comprises the following steps: preparing a nano-ring-shaped magnetic graphene oxide composite material by adopting a microwave method, and coating graphene oxide while forming a magnetic ferroferric oxide nano ring; rigid aromatic amino boron nitride quantum dots are grafted to the surface of thenano-ring-shaped magnetic graphene oxide composite material through a ring-opening reaction. The preparation process is simple and controllable, and the prepared boron nitride quantum dot modified nano-ring-shaped magnetic graphene oxide photocatalytic material is good in thermal stability and has relatively high photocatalytic degradation efficiency and dispersity; when the photocatalytic material is applied to photocatalytic degradation to remove erythromycin and roxithromycin in water, efficient and convenient solid-liquid separation can be realized.

Description

technical field [0001] The invention belongs to the technical field of carbon nanomaterials, and in particular relates to a boron nitride quantum dot modified nano-ring magnetic graphene oxide composite photocatalytic material and a preparation method and application thereof. Background technique [0002] Since the outbreak of the novel coronavirus at the end of 2019, while paying attention to new viruses, super multidrug-resistant bacteria caused by the abuse of antibiotics have also attracted increasing attention. Antibiotics, as a kind of persistent emerging pollutants, will lead to the enhancement of drug resistance of various bacteria in the environment, which will pose a potential safety risk to human health. In recent years, antibiotics such as erythromycin and roxithromycin have been detected from time to time in environmental water samples, including river water, well water, and rainwater. In order to ensure the quality and safety of drinking water for residents, t...
