Robust high-connected rare-earth MOFs as efficient heterogeneous catalysts for CO₂conversion

Abstract

Two series of chemically and thermally stable rare-earth MOFs were constructed using trinuclear [M₃(μ₃-OH)(COO)₆] SBUs and linear dicarboxylate linkers, which feature three-dimensional 12-connected frameworks with an hcp topology. These materials contain a large density of Lewis acidic sites, leading to high catalytic activity towards the cycloaddition of CO₂ and epoxides under mild conditions.
