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.

Nitrogen-rich metal organic frameworks (MOFs) structures have a great potential for the chemical fixation of CO2. In this direction, we utilized highly efficient nitrogen-rich dual linker MOF nickel(ii) as heterogeneous catalyst in solvent-free CO2 into cyclic carbonates at ambient pressure. present work, nickel-MOF, Ni-ImzAdn, was synthesized from imidazole and adenine linkers under hydrothermal conditions (Imz = Imidazole Adn Adenine). The Ni-ImzAdn characterized thoroughly via various physicochemical analyses such FT-IR, SEM, EDX, EDX-mapping, XRD, ICP-OES, BET, BJH, TG-DTA, CO2-TPD, NH3-TPD. with adequate free nitrogen sites exhibit high catalytic activity cycloaddition styrene oxide (93% yield) attributed to synergistic effect strong Lewis acid base on catalyst, which were acquired by NH3-TPD respectively. addition, presented recyclable without significant loss after six reaction cycles low ion leaching (analyzed (ICP-OES)). Thermogravimetry-differential thermal analysis (TG-DTA) showed had stability up 318 °C.

Abstract Despite extensive research into developing efficient and environmentally friendly catalysts for converting CO 2 over the last decade, search a robust cost‐effective catalytic system is ongoing. This study describes applying new using inexpensive ferrate zincate anions immobilized on easily available commercial ion exchange resins (IER) to produce cyclic carbonates from with high efficiency low cost. Two polystyrene‐based anion resins, Amberlyst TM A26‐Cl ( ) Amberlite IRA‐400‐Cl IRA400‐Cl ), were compared. The results demonstrated catalysts’ remarkable activity under mild conditions synergistic effect between polystyrene support active ammonium metallates, presenting scalable, eco‐friendly method carbonate production waste . A Design of Experiment (DoE) approach was implemented optimize cycloaddition reaction scale‐up 5 g batch propylene oxide conducting recycling tests that catalyst retained its four cycles. also explored use various epoxides found terminal produced very good yields. In summary, this introduces cost‐effective, scalable valuable carbonates, leveraging effects supports metallates.
