Abstract

Intercalation phenomena of gas molecules in the interlayer of graphene oxide have been investigated using CO₂, CH₄, H ₂, and N₂ gases. Intercalation of gas molecules is highly affected by the affinity between the hydrophilic surface of GO and target molecules. Among tested gases, CO₂ can only be intercalated. Furthermore, the swelling of interlayer changed the intercalation phenomena. Amounts of intercalated gases are significantly enhanced, and all the gases can be intercalated by retarded dynamics of intercalated water.
