Considering that the greenhouse effect is most concerning environmental issue globally, selective capture and resource utilization of CO2 have attracted widespread attention. Herein, we report a highly robust thulium(III)–organic framework {[Tm2(μ2-OH)(CPPDDA)(H2O)2]·3DMF·2H2O}n (NUC-108), which obtained from exquisite combination undocumented multifunctional clusters [Tm4(μ2-OH)2(COO)10(H2O)4] organic ligands 4,4′-(4-(4-carboxyphenyl)pyridine-2,6-diyl)diisophthalic acid (H5CPPDDA). NUC-108 possesses following unique merits: (i) functional tetranuclear rare-earth serve as nodes, in Tm3+ ions can be activated Lewis sites μ2-OH anions are base sites; (ii) high-porosity zeolite architecture contains three kinds channels: 12.29 × 9.74 Å2 8.92 4.97 along b axis 12.76 8.95 c axis; (iii) uncoordinated pyridine moieties further endow host with functionality; (iv) resistance to weak acidic alkaline aqueous solutions well various solvents. Notably, NUC-108a effectively separate binary CO2/CH4 mixture high adsorption selectivity, should due enough basic groups moieties. Furthermore, under mild conditions without any solvent, also used an effective recoverable catalyst facilitate cycloaddition epoxides aid tetrabutylammonium bromide. Hence, these findings beneficial for guiding development stable active catalysts carbon utilization.
