Abstract

Herein, we report on a new Cu-based MOF material, Cu(2)(dhtp), structurally homologous to the honeycomb-like M(2)(dhtp) series. This has been crystallized under solvothermal conditions using copper nitrate and 2,5-dihydroxyterephthalic acid as an organic linker, being the nature of the co-solvent in the synthesis media an important variable over the final physical properties of the material. The presence of isopropanol as a co-solvent leads to the formation of a pure crystalline phase with textural properties comparable to M(2)(dhtp) homologues. The interesting results in CO(2) adsorption properties of this new material, especially its isosteric heat of adsorption, make it a suitable MOF to be further evaluated under real conditions of industrial CO(2) capture.
