•GO and RGO foams were prepared using a simple and green method, unidirectional freeze-drying.•The porous structure of the foams can be adjusted by changing GO concentrations.•GO and RGO foams show good adsorption efficiency for acetone gas.
Graphene oxide (GO) and reduced graphene oxide (RGO) foams were prepared using a unidirectional freeze-drying method. These porous carbon materials were characterized by thermal gravimetric analysis, differential scanning calorimetry, X-ray photoelectron spectroscopy and scanning electron microscopy. The adsorption behavior of the two kinds of foams for acetone was studied. The result showed that the saturated adsorption efficiency of the GO foams was over 100%, and was higher than that of RGO foams and other carbon materials.
