About Al-MCM-41
Al-MCM-41 is a member of the ExxonMobil M41S family of mesoporous molecular sieves. Researchers at Mobil in the 1980s were on a quest to find better molecular sieves when they discovered a group of nanostructured mesoporous materials. Mobil Composition of Matter (MCM) 41, the hexagonal phase, is a widely used and studied member of this family.
Mesoporous silicates, such as Al-MCM-41, have a large surface area and large pore size within an ordered array of cylindrical mesopores. This morphology increases the likelihood that a reactant molecule in solution can make contact with the surface of a catalyst and react. It also ensures the reactant molecules are small enough to diffuse into the large pores. As such, Al-MCM-41 is an excellent option for use as a catalyst or catalyst support, as an adsorbent, or as a component of guest-host chemistry.
Al-MCM-41 from ACS Material is synthesized via the hydrothermal method and comes calcined and ready to use.
