Study of the Molecular Hydrogen- Zeolites Interaction
An expression of monolayer capacity for hydrogen adsorption was derived on the basis of Ono-Kondo lattice theory. And then, the interaction energies between hydrogen molecules and pore surface atoms in the zeolite were calculated by using Lennard-Jones (12-6) potential model for spherical pores. The results show that the monolayer capacity is dependent on adsorbate–adsorbent and adsorbate–adsorbate interaction energies, and that the interaction energies of hydrogen-zeolite agree with the previously reported isosteric heat of hydrogen on zeolites.
