• Mg-MOF-74
• Breakthrough experiment
• CO2/H2O binary adsorption

Mg-MOF-74 was synthesized through a solvothermal method using Mg(NO3)(2) . 6H(2)O and 2,5-di-hydroxyterephthalic acid as raw materials. The product was then characterized via X-ray diffraction(XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and breakthrough experiments. The results show that pure Mg-MOF-74 with complete structure, regular morphology and excellent CO2 adsorption properties was prepared. It is confirmed in breakthrough experiments that the as-synthesized Mg-MOF-74 maintains a high CO2 adsorption properties in the presence of H2O. Therefore, the prepared Mg-MOF-74 is a suitable candidate for capturing CO2 from wet flue gas stream.
