Abstract Zeolitic octahedral metal oxide is a newly synthesized all‐inorganic zeolitic material and has been used for adsorption, separation, catalysis. Herein, new was characterized. The porous framework established through the assembly of [P 2 Mo 13 O 50 ] clusters with PO 4 linkers. Guest molecules occupied framework, which could be removed heat treatment, thereby opening micropores. pore characteristics were controlled by cations within micropore, enabling adjustment interactions alkynes alkenes. This resulted in good separation performance ethylene/acetylene propylene/propyne even under high temperature humidity conditions. stability enabled efficient recovery reuse without discernible loss performance. Due to relatively weak interaction between adsorbed alkyne adsorbent facilitated highly pure alkyne. feature enhances practical applicability various industrial processes.

Tailoring a MOF with suitable pore windows for the sieving C3H6/C3H8 separation is attractive but challenging, where controlling local framework flexibility by introducing functionality provides solution. In this work, four isoreticular ultramicroporous Zn–triazolate–dicarboxylate frameworks, Zn-ATZ-IP(R) (R = −F, −OH, −NH2, and −CH3) (HATZ 3-amino-1,2,4-triazole; H2IP-R R group functionalized isophthalic acid) variable apertures, were targeted as platforms to study effect of functional groups on their performance. Single-component adsorption isotherms uncovered potential Zn-ATZ-IP(OH)-a hydroxyl adsorbent. Single X-ray diffraction (SXRD) measurements revealed that strong intraframework hydrogen bonds hinder free torsion ATZ– ligand in Zn-ATZ-IP(OH)-a, defining rigid admit C3H6 while exclude C3H8, whereas other give adaptive larger pores allow both C3H8 in. Further, situ XRD suggested temperature alters strength bonds, making ideal room-temperature C3H6/C3H8. This work highlights superiority customizing sustained which advances rational design smart adsorbents energy-efficient light hydrocarbon separations.
