摘要:
以硝酸钾为中心金属离子，1,4-苯二甲酸（H2BDC）、1,3,5-苯三甲酸（H3BTC）及混合物（H2BDC+H3BTC）为有机配体，N,N-二甲基甲酰胺（DMF）为溶剂，采用溶剂热法合成三种K-MOF晶体。通过X射线粉末衍射(PXRD)、红外光谱(FT-IR)、扫描电镜（SEM）及热重(TG)等方法对样品进行表征，考察不同配体对K-MOF的影响。结果表明：K+与H2BDC配位得到的长条状晶体，与H3BTC配位得到粉末状晶体，H2BDC与H3BTC同时存在时，K+优先与H3BTC配位得到粉末状晶体。K-MOF具有良好的热稳定性，在350℃内能保持结构的热稳定性。
Abstract:
3 kinds of K-MOFs were synthesized by solvothermal reaction of K2+ with three ligands (terephthalic acid chelate (H2BDC), trimesic acid (H3BTC) and their mixture（H2BDC+H3BTC）)in DMF and characterized by single-crystal X-ray diffraction analyses, powder X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy (SEM) and thermogravimetric analysis (TG) for textural properties. The results show that K-MOFs derived from H2BDC and H3BTC are stripe crystal and powder crystal, respectively, K+ is inclined to unite with H2BDC to form powder crystal when both H2BDC and H3BTC are present. K-MOFs have high thermo stability, the heat decomposing temperature of which is 350 ℃.
