Abstract

Aiming to improve the acetylene (C₂H₂) storage capability of MOFs, we successfully designed NJU-Bai 17, a new analogue of MOF-505 with an inserted amide functional group which exhibits almost record high C₂H₂ uptakes of 222.4 cm³ g⁻¹ at 296 K and 296 cm³ g⁻¹ at 273 K under 1 bar. This result has been further supported by the determination of the heat of C₂H₂ adsorption and Grand Canonical Monte Carlo (GCMC) and first-principle calculations.
