▎ 摘　　要

The graphene-based aerogel microspheres (GAMs) with a flow-induced microchannel structure were prepared by a combination of emulsification method with the in situ freeze-drying process, followed by thermal reduction. A uniform orientation microchannel structure can be found on the surface of the large GAMs. While, multi-orientation microchannels were observed on the small GAMs. The effective reduction of the GAMs was confirmed by thermogravimetric analysis, Fourier transform infrared spectroscopy, and X-ray photoemission spectroscopy. The hydrophobic GAMs were highly porous with a bulk density ranging from 4.30 to 7.74 mg/cm(3)and exhibited excellent absorption performance for various types of organic solvent and oils. The absorption capacities of the GAMs for oil/solvent ranged from 67 to 133 times to their initial weight, showing great potential applications in oil and chemical spill/leak cleanup.
