The invention relates to a photocatalytic material taking waste polystyrene as aggregate and a preparation method and application thereof. Firstly, dissolving waste polystyrene plastics in cyclohexane, adding a photocatalyst, uniformly stirring, and finally freeze-drying to obtain the foam material. The foam material can be used for treating dye wastewater containing organic matters such as methylene blue, rhodamine B and the like, has the advantages of high photocatalytic efficiency, simple preparation method, capability of avoiding secondary pollution and the like, and has good application prospect. |
