Abstract
A 2D-NLDFT-HS study is performed of the effect the state of oxidation of the graphite matrix has on the parameters of micro-, meso-, and macropore structures of thermally expanded graphite (TEG). A wide range of the stage numbers of graphite intercalation compounds synthesized from natural flake graphite of the same grade is considered, along with the intercalant that is used and the particle size of the original graphite. The 2D-NLDFT-HS model provides a more accurate description of low-temperature nitrogen adsorption/desorption isotherms than other means.
