中文摘要：
合成了骨架带电的类沸石金属-有机骨架材料usf-ZMOF.通过Li＋离子交换将骨架中体积较大的有机阳离子用较小体积的无机阳离子取代,利用X射线衍射（XRD）、扫描电子显微镜（SEM）、热重分析（TGA）等手段对离子交换前后的材料进行表征,并对CO2在其中的吸附性质进行了研究.实验结果表明,Li＋离子交换后材料的比表面积增加,CO2吸附量也增加,与分子模拟预测的结果一致.
英文摘要：
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 ther-mogravimetric 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.
