The invention relates to a preparation method of a Cu-based polyoxometalate-functionalized graphene oxide nanomaterial, comprising the following steps: S1: to boiling (NH 4 ) 6 Mo 7 O 24 ﹒ Add CuSO 4 aqueous solution dropwise to the 4H 2 O aqueous solution and stir and filter in real time to precipitate Cu-based Anderson-type polyacid crystals; S2: ultrasonically disperse graphene oxide in ethanol, then add ethylene diamine to it, heat and react to obtain the function S3: prepare a Cu-based Anderson-type polyacid aqueous solution by using Cu-based Anderson-type polyacid crystals, soak the functionalized graphene oxide in the Cu-based Anderson-type polyacid aqueous solution, and then heat and reflux for 12-14h, The finished product of Cu-based polyoxometalate-functionalized graphene oxide nanomaterial is obtained. Compared with the prior art, the preparation method of the invention is simple, the raw materials are easily obtained, and compared with the traditional heteropolyacid photodegradation reaction requiring an ultraviolet lamp, the prepared catalytic material can be used for the removal of organic pollutants in water under the condition of sunlight. , the catalytic reaction activity is high, and it can be recycled. |
