Effect Of Surface

The BET adsorption isotherm is modified in order to take account of surface heterogeneity. The adsorption isotherm is obtained following the statistical mechanics formalism, proposed by Steele, and the effect of surface heterogeneity is limited to the first layer. A Gaussian adsorption energies distribution function is used to describe surface heterogeneity. The variations of the C parameter, multilayer formation and the inversion of adsorption isotherms are analysed.

Theoretical adsorption isotherms show plateaus reflecting the types of conformer on the graphene surface. Both catechol and phenyl hydroquinone adsorption can be described by our interconvertible statistical mechanical monomer–dimer–trimer model.
