Preparation and Photocatalytic Performance Investigation of g-C3N4/MoS2/CoFe2O4 Ternary Composite Materials

The magnetic material CoFe2O4 has been successfully loaded into g-C3N4/MoS2 binary heterojunction by two steps of ultrasonic composite and heat treatment. Different proportions of g-C3N4/MoS2/CoFe2O4 photocatalytic materials were successfully prepared. The morphology, structure The optical and photocatalytic properties were tested. The results showed that under the condition of ph = 7 and the mass ratio of 10:1, the photocatalytic performance of the photocatalyst material was the best. In the PMS system, the photocatalytic effect reached 98% after 40 min of illumination. The results showed that holes played a major role in the photocatalytic reaction, followed by Hydroxyl radical and SO4-. The research provides ideas for recycling photocatalysts and improving the photocatalytic activity of magnetic materials.
