With the help of modulator synthesis method, a mesoporous Zr-based metalorganic framework, [Zr6O4(OH)(8)(H2O)(4)(TADIBA)(4)]24DMF45H(2)O (DMF = N,N-dimethylformamide, H(2)TADIBA = 4,4'-(2H-1,2,4-triazole-3,5-diyl) dibenzoic acid), namely, JLU-MOF58, was successfully constructed. JLU-MOF58 having reo topology is constructed by the bent ligands with Lewis basic sites and 8-connected Zr-6 clusters with Lewis and Bronsted acid sites. It not only possesses two types of mesoporous cages: octahedral and cuboctahedral (2.76 and 4.10 nm), with a pore volume of 1.76 cm(3) g(-1), but also displays excellent chemical stability in acid and base aqueous phase. Benefiting from the Bronsted and Lewis acid sites, Lewis basic sites, excellent chemical stability, and the mesoporous cages incorporated in the framework, JLU-MOF58 can be regarded as a remarkably efficient heterogeneous catalyst that exhibits excellent catalytic efficiency for CO2 conversion.
