Benchmark single-step ethylene purification from ternary mixtures by a customized fluorinated anion-embedded MOF.

ABSTRACT: Ethylene (C₂H₄) purification from multi-component mixtures by physical adsorption is a great challenge in the chemical industry. Herein, we report a GeF₆^2- anion embedded MOF (ZNU-6) with customized pore structure and pore chemistry for benchmark one-step C₂H₄ recovery from C₂H₂ and CO₂. ZNU-6 exhibits significantly high C₂H₂ (1.53 mmol/g) and CO₂ (1.46 mmol/g) capacity at 0.01 bar. Record high C₂H₄ productivity is achieved from C₂H₂/CO₂/C₂H₄ mixtures in a single adsorption process under various conditions. The separation performance is retained over multiple cycles and under humid co
