NOVELTY - Use of graphene aerogel is claimed in photocatalytic removal of uranium. USE - Graphene aerogel is used in photocatalytic removal of uranium (claimed). ADVANTAGE - The graphene aerogel has excellent photocatalytic performance for uranium, high removal capacity as 1050mg/g, and activity after being recycled 5 times. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for using graphene aerogel in photocatalytic removal of uranium, which involves putting graphene aerogel in solution containing uranium, adding methanol as sacrificial agent, stirring and touching in dark box, and then turning on the light source to perform photocatalytic reaction to remove the uranium; and (2) a method for preparing graphene aerogel for photocatalytic removal of uranium, which involves using graphite as raw material to prepare graphene oxide, and preparing aqueous solution of graphene oxide for later use, stirring graphene oxide aqueous solution ultrasonically, stripping graphene oxide sheets to obtain mixed solution, placing mixed solution prepared at 140-220 degrees C for high-temperature roasting and then cooling, washing and freeze-drying product to obtain graphene aerogel.
