The usf-ZMOF with charged framework is synthesized, and the organic cation in framework is substituted by inorganic lithium ion by ion-exchange method. The structures of the materials before and after ion-exchange are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The CO2 adsorption properties are studied. The experiment data indicate that the specific surface area and the CO2 adsorption capacity of usf-ZMOF are both increased after lithium ions exchange, which is in agreement with the molecular simulation results.
