NOVELTY - Preparation of oil-absorbing carbon sponge, involves adding melamine sponge to graphene oxide, ultrasonically dispersing at 59 kHz at room temperature to obtain 0.5-5 mg/mL dispersion, freeze-drying at -70 degrees C, adding the frozen graphene-oxide-coated melamine sponge to ice, vacuum-drying at 1 Pa for 36-72 hours, and calcining in a reducing atmosphere at 150-400 degrees C for 1-5 hours. USE - Preparation of oil-absorbing carbon sponge (claimed). ADVANTAGE - The method enables simple preparation of superhydrophobic, three-dimensional macroscopic oil-absorbing carbon sponge using reduced amount of graphene oxide, which reduces cost. The obtained sponge has excellent absorption performance and mechanical property.
