Abstract

Abstract: Metal organic frameworks Co1Cu2(BHTC)2 was prepared from biphenyl3,4',5tricarboxylate as organic ligand with hydrothermal method, and then characterized by XRD, SEM, TEM, TGA and FT-IR technology. The effect of temperature and crystallization time on the crystal growth and the growth mechanism of Co1Cu2(BHTC)2 was studied by SEM method. This work provides a new way of the crystal growth of nanoporous material. The results indicate that the crystal morphology changes markedly with the increase of crystallized time. The small hexagonal secondary building units (SBUs) were assembled by sharing the same prism of the tiny crystals, and then aggregated into a bulk hexagonal plate-like crystal.

Key words: Metal organic frameworks , Hydrothermal method , Crystal , Growth mechanism.

摘要： 采用水热合成法,以3,4暞,5飊联苯三羧酸(H3BHTC)为有机配体合成金属有机骨架化合物Co1Cu2
(BHTC)2 ,通过X飊射线粉末衍射(XRD)、扫描电子显微镜(SEM)、投射电子显微镜(TEM)、热重分析(TGA)、傅里叶
红外光谱分析(FT飊IR)等测试手段对晶体进行表征,考察温度、晶化时间对Co1Cu2(BHTC)2 晶体生长的影响,采用
SEM 技术初步探索了Co1Cu2(BHTC)2 晶体的生长机理。实验结果表明,随着时间的延长,晶体的形貌也随之发生
变化,六边形次级结构单元(SBU)通过共享棱的方式具体组装形成更大的六角片状晶体。
