Question

A double-walled porous metalorganic framework as a highly efficient catalyst for chemical fixation of co2 with epoxides

Answer 1

Answer:

Explanation:

A double-walled MOF [Zn5(μ3–OH)2(DBTA)2(H2O)4]·solvents [1, H4DBTA = 2,2′-dihydroxy-1,1′-binaphthyl-3,3′,6,6′-tetrakis(4-benzoic acid)] has been designed and constructed based on a rare Zn5 cluster. The resultant sample has enrichment of porous structure with high BET and Langmuir surface area. By virtue of multiaperture structure and plentiful catalytic sites of Brønsted (−OH) and Lewis acidic (ZnII), MOF 1 is a unique catalyst to synthesize cyclic carbonates from CO2 and epoxides with preferable repeatability.
