Mg-MOF-74 material with a hierarchical pore structure was successfully prepared by regulating the defects through propionic acid. The derived materials were analyzed with X-ray diffraction, scanning electron microscopy, FT-IR, X-ray photoelectron spectroscopy, thermogravimetry analysis, elemental analysis, and nitrogen adsorption. Results show that a low concentration of propionic acid (n DHTA :n PA = 2:1) introduces a mesoporous structure while maintaining the material's crystallinity. This modification significantly increased the specific su...
