| 摘 要： | 首先制备了嫁接氨基的均苯三甲酸,同时以其为原料通过溶剂热法合成了金属有机框架材料Cu_3(NH_2BTC)_2,利用XRD、N_2吸附-脱附、热重、红外、原位红外分析等表征手段对吸附剂进行了表征,并通过固定床测量穿透曲线的方法研究其CO_2吸附性能。结果表明,氨基被成功引入Cu_3(BTC)_2骨架中。氨基修饰的Cu_3(BTC)_2对CO_2有着较高的吸附容量,在10 kPa,50℃的条件下CO_2吸附量为1.41 mmol/g,这源于材料对于CO_2同时存在着物理吸附和化学吸附。

| Abstract: | The metal-organic framework of Cu3(NH2BTC)2 was synthesized by solvothermal method with the prepared grafted amine-based trimesic acid as organic ligand. The synthesized adsorbent was characterized by XRD, N2 adsorption-desorption, thermogravimetry, FT-IR and in-situ FT-IR. The performance of the CO2 adsorption was studied by the breakthrough curve based on the fixed-bed reactor. The results showed that the amine groups had been successfully grafted into the skeleton of Cu3(BTC)2. The CO2 adsorption capacity of Cu3(NH2BTC)2 was improved to 1.41 mmol/g at 10 kPa and 50 ℃. The improvement of CO2 uptake might due to the effect of both the physical and chemical adsorption of CO2. |
