Abstract

A well-designed 3D metal-organic framework with accessible Lewis acid-base sites, [Zn ₂ (PZDC)(1/2ATZ) ₂ (H ₂ O) ₂ ·2.5H ₂ O] (H ₂ PZDC = 3,5-pyrazoledicarboxylic acid, 5-ATZ = 5-aminoterazole) abbreviated as Zn(PZDC)(ATZ), was successfully prepared by incorporating zinc(ii) ions, 3,5-pyrazoledicarboxylic acid and nitrogen-rich 5-aminoterazole. The existence of abundant Lewis bases can increase the chemical affinity to carbon dioxide, thus resulting in their high CO ₂ capture ability. Additionally, the heterogeneous Zn(PZDC)(ATZ) catalyst facilitated the CO ₂ coupling reaction of various epoxides into cyclic carbonates with the aid of Bu ₄ NBr under solvent-free conditions (90 °C, 1 MPa, 6 h); besides, a high TON (131.0) and TOF (21.8 h ^-1 ) of propylene carbonates were obtained. Furthermore, the Zn(PZDC)(ATZ) catalyst also showed good chemical stability and recyclability for seven cycles without a significant catalytic loss. What's more, a plausible catalytic mechanism of synergistic effects derived from Zn(PZDC)(ATZ)/Bu ₄ NBr catalysts for CO ₂ conversion to cyclic carbonate was proposed.
