It is shown that certain metal-loaded zeolites (e.g., Ga-MFI) initially prepared as separate metal-containing and zeolite phases are reducible, resulting in solid-state transfer of the metal to the zeolite. The final material is similar to those initially prepared as unsegregated by methods such as aqueous impregnation. Reduction occurs either through appropriate pretreatment or onstream in...
Gallosilicates isostructural with MFI ([Ga]MFI) with different SiO 2 /Ga 2 O 3 molar ratios were prepared by hydrothermal synthesis and subsequent calcination and conversion to the proton form. Microbalance weight loss determinations both upon H 2 reduction of the calcined [Ga]MFIs and upon reduction of the same materials mechanically mixed with β-Ga 2 O ...
