3D macroscopic superhydrophobic magnetic porous carbon aerogel converted from biorenewable popcorn for selective oil-water separation

3D macroscopic superhydrophobic magnetic porous carbon aerogel (3DSMPC), prepared via carbonization and surface modification process regarding popcorn as the raw materials, showed a low density, transcendent magnetic saturation value and superhydrophobic property, and was used to the selective oil-water separation.77
