NOVELTY - Preparing photocatalytic degradation magnetic graphene oxide composite material involves preparing a graphene oxide dispersion liquid, adding a certain amount of graphene oxide to ethanol, and ultrasonically oscillating 1-2 hours. The mixture is added with 20 ml hydrochloric acid and 10ml water to continue ultrasonic vibration for 1-2h to prepare 2-4g/ml graphene oxide solution. The magnetic core coated with graphene oxide is prepared by adding magnetic core material with graphene oxide solution. The mixture is magnetically stirred. The graphene oxide is encapsulated on the magnetic core to form a magnetic nuclear graphene oxide solution. The catalyst is dispersed and adsorbed on the graphene oxide layer.
