Add-Ons
MIL-101(Cr) (Cr3O(X)(H2O)2(BDC)3, where X = F- or OH-; BDC = 1,4-benzenedicarboxylate) is a high-surface-area, mesoporous metal-organic framework with an augmented MTN zeolite topology. It is composed of trimeric chromium (Cr3O) octahedral building blocks linked by ditopic terephthalate ligands into giant supertetrahedra.
For Gas Absorption & Separation, the key structural features of the MIL-101(Cr) are: (1) Dual Mesoporous Cages: Small Mesoporous Cages: Internal diameter of ~ 29 Å with pentagonal window apertures of 12 Å. Large Mesoporous Cages: Internal diameter of 34 Å with hexagonal window apertures of ~ 16 Å. (2) Ultra-High Porosity: BET Surface Area: Typically 3000–4200 m2/g surpassing MIL-100 and UiO-66). Pore Volume: 1.40–2.10 cm3/g. (3) Open Lewis Acidic Cr3+ Sites: Thermal activation removes terminal water and fluoride/hydroxyl species from the Cr3(u3-O) clusters, generating a high density of coordinatively unsaturated Lewis acidic Cr3+ sites (~ 3.0 mmol/g). (4) Chemical & Hydrothermal Resilience: The kinetically inert d3 electronic configuration of Cr3+ imparts high resistance to moisture, boiling water, organic solvents, and acid-gas exposure (SO2, H2S). It remains thermally stable up to ~ 400°C in air/inert environments.
