通过将配体均苯三甲酸 H 3 BTC 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。
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 tempera-ture.SEM was used to investigate the formation of Cu3 (BTC)2 particles.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 pro-vides a straight forward and energy saving method for the preparasion of Cu3 (BTC)2 .
