摘　　要：在水热条件下,利用1,2,3-丙烷三羧酸(H 3ptc)、1,10-邻菲罗啉(phen)与醋酸镉合成得到一例金属有机骨架材料Cd(Hptc)(phen)。晶体结构分析表明,双核镉单元通过4个丙烷三羧酸氢根配体的桥联作用形成沿[100]方向的一维链,链与链之间通过π…π堆积和氢键作用完成三维超分子构筑。以不同染料为目标降解物,考察标题配合物的光催化降解性能。结果表明,在可见光照射300 min后,该催化剂对MB有较好光催化降解性能,去除率达75.3%,降解反应符合一级动力学过程。A metal-organic framework,Cd(Hptc)(phen),was synthesized by 1,2,3-propane tricarboxylic acid(H 3ptc),1,10-phenanthroline(phen)and cadmium acetate under the hydrothermal condition.Crystal structure analysis revealed that dinuclear cadmium units were linked into one-dimensional chains along the direction[100]through the bridging of four propane tricarboxylate ligands.These chains were further interlinked into three-dimensional supramolecular assemblies viaπ…πstacking and hydrogen bonding interactions.Taking different dyes as the target degradation substances,the photocatalytic degradation performance of the title complex was investigated.The results demonstrated that the catalyst exhibited significant photocatalytic degradation of methylene blue(MB),achieving a removal rate of 75.3%after 300 min of visible light irradiation.The degradation reaction accorded with the first-order kinetic process.
