摘要：

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, S(Hw) and S(Hs). The stronger sorption sites S(Hs) which predominated at higher gallium dispersion, corresponded probably to the most effective surface configuration for gallium in the aromatization of n-butane.
