UiO-66 (Universitetet i Oslo-66, Zr6O4(OH)4(BDC)6, where BDC = 1,4-benzenedicarboxylate) is a benchmark zirconium-based metal-organic framework (MOF). Its framework is constructed from 12-connected hexanuclear zirconium oxo-clusters (Zr6O4(OH)4) coordinated to 12 terephthalate linkers in a face-centered cubic (fcu) topology, endowing it with some of the highest chemical, thermal, and mechanical stabilities known in MOF chemistry.
The key structural features of the UIO-66 are: (1) Dual-Cage Architecture & Pore Apertures: Octahedral Cages: Central diameter of ~ 11 Å; Tetrahedral Cages: Central diameter of ~ 8 Å; Triangular Window Apertures: Pore openings of ~ 6.0 Å, facilitating molecular diffusion of small gas molecules while providing size-selective exclusion pathways. (2) Exceptional Stability Matrix: Thermal Stability: Stable up to ~ 450–500°C in air/inert environments due to strong Zr(IV)–O ionic/covalent coordination bonds. Aqueous & Acidic Stability: Highly resistant to boiling water, high-humidity gas streams, and acidic media (pH=1–9), avoiding the structural collapse common to Cu- or Zn-based frameworks. Mechanical Resilience: Can withstand pelletization and hydrostatic compaction pressures up to several thousand bar without loss of crystallinity. (3) Textural Properties: BET Surface Area: Typically 1100–1500 m2/g (pristine/ideal framework). Pore Volume: 0.45–0.55 cm3/g (increases with defect engineering).
