The synthesis and characterization of metallo-titanium silicate analogs (M = Al or Fe) with MEL structure are reported. The simultaneous incorporation of both M[sup 3+] (Al[sup 3+] or Fe[sup 3+]) and Ti[sup 4+] in the MEL framework provides dual catalytic properties in both oxidation (e.g., oxyfunctionalization of n-hexane) and acid catalyzed reactions (e.g., ethylbenzene disproportionation and m-xylene isomerization). The [M, Ti]-MEL molecular sieves, compared to the [M]-MEL analogs, were (i) more resistant towards deactivation in ethylbenzene disproportionation and m-xylene isomerization and (ii) less para selective in the latter reaction. 39 refs., 6 figs., 3 tabs.
