摘　　要：Copper （II） dicarboxylate, MIL-53, metal-organic framework synthesized hydrothermally has been used for the first time as an adsorbent for methane gas adsorption. Methane adsorption capacity of MIL-53（Cu） was increased to about 8.52 mmol·g-1 at 298 K and 35 bar for methane storage. The adsorbent was characterized by X-ray diffraction （XRD）, Brunauer-Emmet-Teller （BET） method, Fourier transform infrared （FT-IR）, thermo gravimetric analysis （TGA） and scanning electron microscopy （SEM）. The adsorption property of CH4, on MIL-53（Cu） was investigated by volumetric measurement. The enhancement of CH4 adsorption capacity of MIL-53（Cu） is attributed to the increase of micropore volume of MIL-53（Cu）.Copper （II） dicarboxylate, MIL-53, metal-organic framework synthesized hydrothermally has been used for the first time as an adsorbent for methane gas adsorption.
