摘要
以SDBS为模板剂,采用水热合成法制备了不同比例的双金属HP-MOF-74(Zn_(x)Ni_(1-x))材料,利用XRD、FT-IR、SEM等对其物化性能进行了研究;以烟道气CO_(2)和N_(2)为吸附质,使用静态容量法在273 K和298 K处测试了三种不同HP-MOF-74(Zn_(x)Ni_(1-x))材料上CO_(2)和N_(2)的等温线;根据理想吸附溶液理论(IAST)估算了CO_(2)/N_(2)二元混合物的吸附选择性;此外,使用克-克方程计算了等量吸附热(QST)。
The SDBS is used as the templates to synthesize different ratio bimetallic HP-MOF-74(Zn_(x)Ni_(1-x))via a solvothermal synthesis method.The structure and physicochemical properties of HP-MOF-74(Zn_(x)Ni_(1-x))are characterized by XRD,FT-IR,SEM,et al.Taking the flue gas CO_(2)and N_(2)as adsorbates,the isotherms of CO_(2)and N_(2)on the three different HP-MOF-74(Zn_(x)Ni_(1-x))are measured by using the static volumetric capacity method at 273 K and 298 K.The isotherms and adsorption selectivity for CO_(2)/N_(2)binary mixtures are estimated on the basis of ideal adsorbed solution theory(IAST).Additionally,the isosteric heat of adsorption(Qst)is calculated by fitting the single–component adsorption isotherm at different temperatures(273 K and 298 K)based on the Clausius–Clapeyron equation.
