基于三氮唑衍生物的MOFs杂化材料合成及其性能研究
摘要
MOFs材料具有大的孔隙、比表面积和丰富的拓扑结构，同时还具有规则性孔道和可调控性孔径的特点，因此MOFs材料在染料吸附方面的性能远优于传统多孔材料，可以将其作为吸附剂吸附染料。本毕业论文的主要内容是，在配体合成过程中通过多元羧酸引入羧基配位点，成功合成了基于多元羧酸和三氮唑的有机羧酸氮杂环类配体。同时用上述配体分别与钴、锰两种金属离子构筑新型MOFs杂化材料，并探究新型MOFs杂化材料在染料吸附与分离方面的性质。该MOFs杂化材料的晶体合成采用水热法，在150 ℃ 和160 ℃ 两种温度，72 h 的条件下，利用不同配比的甲醇与水溶剂成功合成了三种新型的单晶化合物。主要使用了X射线单晶衍射表征了晶体结构，分析了合成的单晶化合物在染料 *51今日免费论文网|www.51jrft.com +Q: ^351916072^

SYNTHESIS AND CHARACTERIZATION OF MOFS HYBRID MATERIALS BASED ON TRIAZOLE DERIVATIVES
ABSTRACT
MOFs material has large pores, specific surface area and rich topological structure, as well as regular channels and adjustable pore sizes. Therefore, the performance of MOFs material in dye adsorption is much better than that of traditional porous materials, and it can be used as an adsorbent to absorb dyes.The main content of this thesis is to successfully synthesize organic carboxylic acidazacyclic ligands based on polycarboxylic acid and triazole by introducing carboxylic ligands in the ligand synthesis process.At the same time, the new MOFs hybrid materials were constructed with the abovementioned ligands and cobalt and manganese metal ions respectively, and the properties of the new MOFs hybrid materials in dye adsorption and separation were investigated.The crystal synthesis of the MOFs hybrid material was carried out by hydrothermal method. Under the conditions of 150 ℃ and 160 ℃ for 72 h, three new monocrystalline compounds were successfully synthesized by methanol and water solvent in different proportions.Xray single crystal diffraction was used to characterize the crystal structure, and the performance of the synthesized single crystal compound in dye adsorption and separation was analyzed. Meanwhile, the influence of the target single crystal compound on the adsorption effect of methyl orange dye under different temperature, pH value and adsorption time was investigated.In terms of dye adsorption and separation properties, the three new monocrystalline compounds have good adsorption properties, showing the broad prospect and potential of MOFs material in the treatment of organic dye molecules in wastewater discharge.
