Synthesis and Catalytic Performance of Al-MCM-48 and Ti-MCM-48
View through CrossRef
Mesoporous sieves MCM-48 with hetero atom were synthesized by adding aluminum and titanium sources
through hydrothermal method. The results showed that MCM-48 could be synthesized respectively by adjusting exactly
the alkalinity of synthesis gel. The conversion rate of DIPB on Al-MCM-48 increased to 80% after 9 h and the selectivity
of IPB was 97%. The conversion rate of styrene on Ti-MCM-48 increased to 9% after 8 h and the selectivity of
benzaldehyde was 85%. The available active sites, which were introduced by aluminum and titanium atoms, were
effectively utilized for catalyst reaction due to the presence of mesopores in Al-MCM-48 and Ti-MCM-48.
