“…The retention time for butene isomer GC separation depended on two factors: the accessibility of adsorbates to the pores and the enthalpy of adsorption after the molecules accessed the pores. In spite of the comparable ∆H ads for cis and trans-2-butene, a result of their similar chemical natures, the molecule shape and size were the key factors in determining the adsorption selectivity [79].…”

The desire to customize the properties of a material through complete control over both its chemical and architectural structure has created a constant and persistent need for efficient and convenient characterization techniques. Inverse gas chromatography (IGC) is considered a useful characterization method for probing the material’s surface properties, like its enthalpies of adsorption, which are the key stimulus components for their adsorption performance. Here, we conclusively review the significance of a less common application of the IGC technique for the physicochemical characterization of metal-organic frameworks (MOFs), which are an innovative subclass of porous materials with matchless properties in terms of structure design and properties. This review focuses on the fundamental theory and instrumentation of IGC as well as its most significant applications in the field of MOF characterization to shed more light on this unique technique.

“…From the point of view of the adsorption mechanism, the efficient separation of gas mixtures by MOFs adsorbents usually depends on the thermodynamic separation based on interaction force, 26,27 kinetic separation determined by adsorption rate, 28–30 molecular sieving separation, 31,32 and gate‐opening flexible separation 33,34 .

Efficient separation of 1,3‐butadiene fromC4hydrocarbons by flexible metal–organic framework with gate‐opening effect

et al. 2022

Efficient and economical separation of 1,3‐butadiene (C4H6) from C4 hydrocarbons is imperative yet challenging in industrial separation processes. Herein, a guest‐induced flexible Mn‐bpdc metal–organic framework (MOF) has been employed to separate C4H6 from C4 hydrocarbons, including n‐butene (n‐C4H8), iso‐butene (iso‐C4H8), n‐butane (n‐C4H10), and iso‐butane (iso‐C4H10). Significantly, C4H6 can instantaneously induce gate‐opening of Mn‐bpdc MOF at 0.13 bar and 298 K, thus significant amounts of C4H6 can be adsorbed, while other C4 hydrocarbons cannot induce the gate‐opening even at 1 bar. The uptake selectivities of Mn‐bpdc MOF for C4H6/n‐C4H8 and C4H6/iso‐C4H8 are up to 40.0 and 45.0 at 298 K and 1 bar, respectively, both surpassing all the reported adsorbents. In addition, breakthrough experiments verify that C4H6/n‐C4H8, C4H6/iso‐C4H8, C4H6/n‐C4H10, C4H6/iso‐C4H10, C4H6/n‐C4H8/n‐C4H10, and C4H6/iso‐C4H8/iso‐C4H10 mixtures can be efficiently separated. More importantly, Mn‐bpdc possesses excellent water stability and outstanding regeneration ability for C4H6 separation, making it a new benchmark for C4H6 purification.
