Zeolitic Tetrazolate–Imidazolate Frameworks with SOD Topology for Room Temperature Fixation of CO2 to Cyclic Carbonates

Presented here is an SOD-type zeolitic tetrazolate–imidazolate framework (ZTIF-8) based on 5-methyltetrazole (5-Hmtz) and 2-methyimidazole (2-Hmim) ligands. Owing to the uncoordinated N-sites on the framework, ZTIF-8 has shown high chemical fixation of CO2 to cyclic carbonates at room temperature and ambient pressure.
