Abstract
Gallium species which were incorporated initially in the oxide form, were all in the (+3) oxidation state in the hybrid catalyst and exhibited two types of hydrogen chemisorption sites, SHw and SHs. The stronger sorption sites SHs which predominated at higher gallium dispersion, corresponded probably to the most effective surface configuration for gallium in the aromatization of n-butane.
