Metal organic framework (MOF) as a typical porous functional material with uniform and ordered pore structure,have received extensive attention in the field of carbon dioxide (CO2) adsorption.A simple hydrothermal synthesis method was used to prepare NH2-MIL-101(Cr).The structure and properties were characterized by X-ray diffraction (XRD),fourier infrared (FTIR),nitrogen (N2) adsorption-desorption isotherms.At 25℃,the maximum adsorption capacity of NH2-MIL-101 (Cr) for CO2 and N2 was 1.6 and 0.08 mmol·g-1,respectively.In addition,the mechanism of CO2 adsorption was explored through in situ diffuse reflectance infrared fourier transform spectroscopy (in situ DRIFTS).A reference was provided for development of more efficient CO2 adsorbent materials in the future.
