Abstract

The invention belongs to the field of photocatalysis, in particular to a preparation method of a graphite-type carbon nitride composite nickel ferrite magnetic photocatalysis material. The magnetic nickel ferrite is bound to graphite carbon nitride by chemical adsorption method, wherein the mass ratio of graphite carbon nitride and nickel ferrite is 1:5~1:25, and the synthesis steps are as follows: Nitriding with a certain mass ratio Add carbon and nickel ferrite to anhydrous ethanol to disperse and stir for a period of time and then heat treatment at a certain temperature. The catalyst prepared by the invention has good magnetic properties, dispersibility and stability, and can still maintain high catalytic activity after five photodegradation cycle experiments. The g-C3N4 / NiFe2O4 composite photocatalyst is excited under visible light to generate photoinduced electrons and holes, and interacts with hydrogen peroxide to undergo a photo-Fenton reaction to achieve efficient degradation of methylene blue.
