Abstract

The invention belongs to the technical field of preparation of photocatalytic materials and particularly relates to a visible-light responsive magnetic photocatalytic material and a preparation method thereof. The visible-light responsive magnetic photocatalytic material provided by the invention is formed by forming a heterojunction through loading nickel ferrite on the surface of bismuth oxide; the molecular formula is NiFe2O4 / Bi2O3 and the structural form is that nickel ferrite grains are compounded on the surface of the rod-shaped bismuth oxide. The visible-light responsive magnetic photocatalytic material provided by the invention has the good photocatalytic efficiency under the illumination of visible light; in the process of degrading tetracycline, the degradation efficiency is up to 90.78% when an optimal preparation condition is utilized; meanwhile, the separation of a catalyst and a reaction system is convenient to realize under an applied magnetic field, so that the visible-light responsive magnetic photocatalytic material has a good industrial application prospect.

Description

technical field

[0001] The invention belongs to the technical field of photocatalytic materials, and in particular relates to a magnetic photocatalytic material responsive to visible light and a preparation method thereof. Background technique

[0002] Antibiotics are a class of chemicals that are widely used to prevent and control viral diseases in humans and animals, and to promote the growth of animals and plants. Antibiotics cannot be completely absorbed during use, and a large amount of residual parts enter the environment, resulting in an increase in the background of antibiotics and the emergence of drug resistance. In recent years, antibiotics have been continuously detected in the water environment, which has caused potential harm to the ecological environment and human health. Therefore, how to eliminate antibiotic pollution in the water environment has become an urgent problem to be solved. Degradation of antibiotics can be achieved by electrochemical methods, bi...
