Publisher Summary This chapter presents diffuse reflectance infrared Fourier transform (DRIFT) study of dinitrogen and dihydrogen adsorption on lithium (Li + ) and sodium (Na + ) forms of low silica X (LSX) zeolite. Adsorption of H 2 at 77 K on Li–LSX zeolite with DRIFT control of the perturbation of adsorbed molecules has discriminated three different types of adsorption sites. Two of them are attributed to H 2 adsorption on Li + ions localized in the supercages of the zeolite framework at S III and S III ’ sites while the latter one belongs to H 2 adsorption on Li + ions at S II sites. Adsorption of N 2 by Li + ions at S III and S III ’ sites are the strongest resulting in a decrease of intensity of the corresponding DRIFT bands from adsorbed H 2 .
