Published: April 3, 2025

Overcoming the trade-off effects between adsorption capacity, selectivity, and enthalpy of an adsorbent is very important but remains a huge challenge. Here, we report flexible metal-organic framework (FJI-H36); it can selectively adsorb Xe from Xe/Kr mixtures with high capacity low enthalpy. Structural analyses show that such excellent performances come adaptive contraction framework; pore shrinkage enhance interactions adsorbed offset some heats. For SF6/N2 mixtures, FJI-H36 also performance SF6 through contraction, resulting in both selectivity This not only provides new for purification Xe/Kr/SF6 offers potential solution to overcome trade-offs among specific adsorbent.

As the focus evolves from structure discovery/characterization (what it is) to property/performance exploration is for), pursuit of stable functional metal-organic frameworks (MOFs) has been ongoing in terms both fundamental research and industrial implementation. Under guidance crystal engineering principles, a plethora developed pyrazolate MOFs (metal pyrazaolate frameworks, MPFs) featuring strong coordination M-N bonding. This attribution helps them retain their structures functions under alkaline conditions required for practical use. Based on poly-topic ligands, various classic MOFs, such as Co(bdp), Fe2(BDP)3, Ni8L6, PCN-601, BUT-55, name few, have revealed fascinating architectures, intriguing properties, record-breaking performances applications during past decade. review will present full scope MPFs date: (1) superiority significance constructing through approach, (2) synthetic strategies adopted building and/or modifying MPFs, (3) structural features stability MPF community, (4) potential energy environmental related fields. The future opportunities are also discussed designing next-generation smart materials. Overall, this attempts provide insights guidelines customization pyrazolate-based specific purposes, which would promote development porous materials addressing societal challenges.
