Metal-alkyl species are formed on interaction of small alkanes with gallium oxide: Evidence from solid-state NMR

► Ga-alkyl species form at C1-C3 alkane adsorption on gallium oxide. ► Ga-alkyl species form at C1-C3 alkane adsorption on gallium-modified zeolite BEA. ► 13C CP/MAS NMR provides the evidence for the formation of surface Ga-alkyl species.
