Add-Ons
MIL-100(Al) (Al3O(X)(H2O)2(BTC)2, where X = OH-, Cl-, or F-; BTC = benzene-1,3,5-tricarboxylate}) is a lightweight, mesoporous aluminum-based metal-organic framework with an MTN zeolite-type topology. Built from inorganic u3-oxo-centered aluminum trimers (Al3O) bridged by rigid, tritopic trimesate linkers into giant supertetrahedra, it combines high pore volume and strong Lewis acidity with non-toxicity, high hydrothermal stability, and lower raw material costs.
For Gas Absorption & Separation, the key structural features of the MIL-100(Al) are: (1) Hierarchical MTN Dual-Mesoporous Network: Small Mesoporous Cages: ~ 25 Å internal diameter with pentagonal window apertures of ~ 4.7-5.5 Å. Large Mesoporous Cages: ~ 29 Å internal diameter with hexagonal window apertures of ~ 8.6 Å. (2) Thermal & Hydrothermal Resilience: The strong ionic/covalent Al(III)–O coordination bond yields thermal stability up to~ 350–380°C in air/inert environments. It withstands boiling water, repeated humidity cycling, and organic solvents without framework hydrolysis. (3) Lewis Acidic Al^{3+} Sites: Thermal evacuation strips coordinated terminal water molecules from the Al3O trimers, exposing hard Lewis acidic Al^{3+} open metal sites that strongly interact with polar, polarizable, or basic guest molecules.
