摘要： 通过微波加热合成法利用1,3,5-均苯三甲酸（H3btc）与金属Zn(NO3)2·6H2O高效合成一例多孔MOFs。通过X-射线衍射仪对化合物表征，并对其热稳定性及吸附性质进行研究。实验结果表明：化合物1具有贯穿型三维孔道，具有55.8%的孔隙体积和永久孔隙度。并对其进行气体吸附研究，发现在低温下对CO2的吸附效果远超过N2。其最大吸附量为251.4 cm3·g-1，BET比表面积为1124.1 m2·g-1。此外，化合物1能够有效在混合染料的水溶液中选择性吸附甲基蓝染料。静电相互作用在染料吸附中起着突出的作用。具有高吸附时效及高吸收率，并在三个周期内对MB分子仍然具有较高的有效去除能力。对低浓度气相碘可实现快速高效吸附行为，其最大吸收量可达0.39271 g·g-1。

Abstract: A case of porous MOFs was synthesized by microwave heating method using 1,3, 5-trimeric acid (H3btc) and metal Zn(NO3)2·6H2O. The compounds were characterized by X-ray diffractometer, and their thermal stability and adsorption properties were studied. The experimental results show that compound 1 has a penetrating three-dimensional channel with 55.8% pore volume and permanent porosity. It is found that the adsorption effect of CO2 at low temperature is much higher than that of N2. The maximum adsorption capacity is 251.4 cm3·g-1, and the specific surface area of BET is 1124.1 m2·g-1. In addition, compound 1 can effectively selectively adsorb methyl blue dyes in aqueous solutions of mixed dyes. Electrostatic interaction plays a prominent role in dye adsorption. It has high adsorption aging and high absorption rate, and still has high effective removal ability of MB molecules in three cycles. It can achieve rapid and efficient adsorption behavior for low-concentration gaseous iodine, and its maximum absorption capacity can reach 0.39271 g·g-1.
