| description | The invention discloses a composite material for dye degradation and a preparation method thereof. The preparation method of the composite material for dye degradation comprises the following steps: S1, preparing raw materials including cellulose, inorganic salt, distilled water, a solvent, a dispersing agent and a poor solvent; S2, activating cellulose, vacuumizing and drying the activated cellulose, adding the activated cellulose into a solvent, and stirring under the protection of inert gas to obtain pretreated cellulose; S3, adding inorganic salt into distilled water, fully mixing and stirring, adding the pretreated cellulose, adding a dispersing agent for dispersing, adding a poor solvent for washing, dispersing in the poor solvent, performing filtering, and putting the mixture into a vacuum drying device for vacuum drying to obtain a composite material for dye degradation. According to the invention, by adopting the renewable cellulose with low price as the raw material, the cost is greatly reduced, and |
