摘要：

N2 edsorption , mercury porosimetry and scanning electron microscope SEM ) were chosen in this work to investigate the pore size distribution, pore shape, speeific surface area and pore volume of expanded graphite, a new type of porous carbon material. The results showed that expanded graphite is dominated by middle and large sizes of wedge-pores with cross section of slit or polygon. It has a relatively medium specific surface area and may be suitab1e for adsorbing large molecules.
