▎ 摘　　要

NOVELTY - Graphene oxide sponge is claimed. The graphene oxide sponge having porous structure and uniformly dispersing graphene oxide on the surface of the screen is prepared by supporting graphene oxide on polyvinyl alcohol while mechanical stirring, reacting with formaldehyde to obtain graphene oxide sponge, and drying the obtained graphene oxide sponge in a vacuum dryer to obtain final product. USE - Used as graphene oxide sponge. ADVANTAGE - The method: has very large adsorption amount of 2992.4 mg/g, simple process and low cost.
