Subsequently, three isostructural Zr-MOFs, including the parent structure Zr(H₂L), amino-decorated Zr(H₂L) (NH₂-Zr(H₂L)), and fluorine and amino bi-decorated Zr(H₂L) (F-NH₂-Zr(H₂L)), are employed as the platform for systematically investigating the effect of Lewis basic groups on the CO₂ adsorption and separation behavior, more importantly the CO₂ chemical fixation. Benefitting from the decorated Lewis basic groups, not only the CO₂ adsorption enthalpy and selectivity over CH₄ of NH₂-Zr(H₂L) and F-NH₂-Zr(H₂L) are improved, but also their catalytic activities for cycloaddition of CO₂ to form cyclic carbonates are significantly enhanced. Among them, F-NH₂-Zr(H₂L) exhibits the most effective performance for cycloaddition of CO₂ and styrene epoxide, which can be attributed to the strong polarization between the CO₂ molecule and the framework of F-NH₂-Zr(H₂L). Under a mild condition, the yield of F-NH₂-Zr(H₂L) for cycloaddition of CO₂ with styrene epoxide can reach up to 97%, which surpasses most of the reported MOFs-based catalysts.]]> Fri 22 Jul 2022 13:20:26 AEST ]]>
