Abstract: β-cyclodextrin-based graphene aerogels (C-GAs) were prepared with graphene oxide (GO) as framework and β-cyclodextrin (β-CD) as carbon sourceby using the hydrothermal method.Specific surface analysis instrument revealed the pore structure and gas adsorption of C-GAs.The results indicated that C-GAs had higher specific surface areas of 537m2/g and total pore volumes of 0.750cm3/g.The prepared C-GAs with the mass ratio of 0.5(β-CD/GO) exhibited the highest adsorption capacity of 44.73mg/g for CO2,6.82mg/g for CH4 and 1.17mg/g for H2,respectively.C-GAs showed the stronger adsorption capacity and excellent adsorptive selectivity.The craft process was convenient,green and safe,which will be utilized in methane treatment,beverage processing,agricultural product protection and supercritical extraction.
