【摘要】 通过将配体均苯三甲酸H3BTC转化为均苯三甲酸钾,在室温条件下快速获得了金属有机骨架材料中的经典化合物Cu3(BTC)2(HKUST-1),并通过SEM跟踪了晶体的生长过程。粉末XRD测试结果表明化合物为纯相,并具有较高结晶度,TGA测试结果表明产物可稳定存在至300℃,N2吸附测试显示出产物具有高的比表面积及孔容积。研究工作为Cu3(BTC)2这一重要化合物提供了一条简便及低能耗的合成方法。更多还原

【Abstract】 By converting 1,3,5-benzenetricarboxylic acid into potassium 1,3,5-benzenetricarboxylate,Cu3(BTC)2,one of the most well-known metal-organic frameworks,was synthesized rapidly at room temperature. SEM was used to investigate the formation of Cu3(BTC)2particles. Powder XRD pattern indicates that the product is in pure form with a high crystallinity. The TGA data reveal that the crystal structure is stable up to 300 ℃. N2 sorption measurements indicate large BET surface areas and total pore volumes. This research provides a straight forward and energy saving method for the preparasion of Cu3(BTC)2.更多还原
