文摘Density functional theory(DFT)based ab-initio calculations were used to study formaldehyde(CH_2O)adsorptive behavior on graphene sheet.The results indicate that formaldehyde molecule is weakly bound to graphene with small adsorption values(approximately-0.064eV),but the interaction between CH_2O and graphene sheets can be greatly strengthened by means of doped atoms,which can provide a basis for the development of CH_2O storage materials.
