The efficient separation of C2H2 from C2H2/CO2 or C2H2/CO2/CH4 mixtures is crucial for achieving high-purity (>99%), essential in producing contemporary commodity chemicals. In this report, we present ZNU-12, a metal–organic framework with space-partitioned pores formed by inorganic fluorinated anions, highly and separation. framework, partitioned SiF62– anions into three distinct cages, enables both high capacity (176.5 cm3/g at 298 K 1.0 bar) outstanding selectivity over CO2 (13.4) CH4 (233.5) simultaneously. Notably, achieve record-high productivity (132.7, 105.9, 98.8, 80.0 L/kg 99.5% purity) (v/v = 50/50) 1/1/1, 1/1/2, 1/1/8) through cycle adsorption–desorption breakthrough experiments recovery rates. Theoretical calculations suggest the presence potent "2 + 2" collaborative hydrogen bonds between two hexafluorosilicate (SiF62–) confined cavities.

Selective separation of acetylene (C2H2) from carbon dioxide (CO2) and ethylene (C2H4) remains a significant challenge in the field gas separation. Non-thermally driven technology based on metal–organic frameworks (MOFs) offers an efficient environmentally friendly approach. Herein, Ni-based anionic MOF (iMOF-1A) was employed for first time. The differential recognition various molecules is enhanced by suitable pore sizes, accessible aromatic rings, cations outside framework. Experimental results demonstrate that iMOF-1A exhibits exceptional uptake ratios C2H2/CO2 (2.27) C2H2/C2H4 (1.48), which surpass those most previously reported materials. Furthermore, ideal adsorbed solution theory (IAST) selectivity calculations display promising theoretical performance, supported molecular simulations. Breakthrough experiments further validate not only effectively separates mixtures but also excellent performance humidity stability C2H2/C2H4/CO2 ternary mixtures.
