摘要: Mesoporous material SBA-15 was modified by alumina via an atomic layer deposition method and used for the reaction of methanol dehydration. The samples were characterized x-ray powder diffraction, transmission electron microscopy, solid-state nuclear magnetic resonance, Brunauer-Emmett-Teller (BET) methods. results revealed that Al had been successfully incorporated into framework after modification. Both Bronsted Lewis acid sites coexist on alumina-modified surface. with Al2O3/SiO2 ratios 8 wt% has higher activity compared titania- tungsten oxide-modified SBA-15.
