Abstract

One-step C₂H₄ purification from a mixture of C₂H₂/C₂H₄/C₂H₆ by physical adsorption separation was realized via creating an ethane trap in MOF NTUniv-63 by the utilization of a ketone-decorated semirigid ligand, which has further been verified by the breakthrough experiment, isosteric heats of adsorption (Q_st), and Grand Canonical Monte Carlo (GCMC) modeling.
