Aj. Ramirez-pastor et al., Statistical thermodynamics of linear adsorbates in low dimensions: Application to adsorption on heterogeneous surfaces, LANGMUIR, 15(18), 1999, pp. 5707-5712
Exact forms for the thermodynamic functions of linear adsorbates in one dim
ension are presented in the lattice gas description of localized adsorption
with multisite occupancy. A modified form of the adsorption isotherm for l
inear adsorbates on heterogeneous substrates is proposed, by introducing th
e rigorous expression for the Helmholtz free energy of the adlayer on a hom
ogeneous one-dimensional lattice into the multisite occupancy model propose
d by Nitta et al. (1984). Comparisons between the original and modified iso
therms and Monte Carlo simulations for dimers and 4-mers on heterogeneous s
urfaces with two type of sites are carried out. Fitting of the adsorption i
sotherm to experimental data for CO, N-2, and O-2 on zeolites 5A and 10X is
performed and discussed as well.
