Frequent offshore oil spill accidents, industrial oily sewage and the indiscriminate disposal of urban oily sewage have caused serious impacts on human living environment and health. The traditional oil-water separation methods not only cause easily environmental secondary pollution, but also waste of limited resources. Therefore, in this work, 3D graphitic carbon sphere foams (3D-foams) possessed three-dimensional porous structure with pore size distribution of 25~200 μm, and high porosity of 62% were prepared for oil adsorption via foam-gel casting method using graphitic carbon spheres as starting materials. The resulted indicated that the water contact angle of as-prepared 3D-foams was 130°. The contents of graphitic carbon spheres (GCS) greatly influenced the hydrophobicity, water contact angle (WCA) and microstructure of the as-prepared samples. The adsorption capacities of as-prepared 3D-foams for paraffin oil, vegetable oil and vacuum pump oil were about 12~15 g/g, which were 10 times of that graphitic carbon spheres powder.
