摘要
结合科研工作设计了一个综合性大学化学实验——多孔MOFs(UiO-66,[Zr_(6)O_(4)(OH)_(4)(BDC)_(4)]n(H2BDC=对苯二甲酸)和UiO-68,[Zr_(6)O_(4)(OH)_(4)(ATDA)_(4)]n(H_(2)ATDA=2′-氨基-[1,1′:4′,1″-三联苯]-4,4″-二羧酸))的合成、表征及相关性能研究。该设计实验选择具有不同长度的配体与锆离子组装得到晶态材料,整个实验过程包括有机合成、溶剂热合成、X射线单晶衍射和粉末衍射、红外光谱、热重分析等内容,综合了各大化学知识点于一身。经过此实验,学生不仅能有效了解并掌握MOFs材料的合成、性能测试与相关仪器的操作,还可做到理论结合实际、基础知识结合现代科研手段,培养学生的化学科研素养。
Combined with the author’s research work,we recommend a comprehensive university chemistry experiment,which is about the synthesis,characterization and related properties of metal-organic frameworks(MOFs)(UiO-66,[Zr_(6)O_(4)(OH)_(4)(BDC)_(4)]n,H2BDC=terephthalic acid and UiO-68,[Zr_(6)O_(4)(OH)_(4)(ATDA)_(4)]n,H2ATDA=2′-amino-[1,1′:4′,1′-triphenyl]-4,4′-dicarboxylic acid).In this experiment,by assembling ligands of different length with zirconium ion,crystalline materials are synthesized,and the entire experimental process includes organic synthesis,solvothermal synthesis,X-ray single crystal diffraction and powder diffraction,infrared spectroscopy and thermogravimetric analysis,which integrates lots of chemical knowledge.After this experiment,students can not only understand and master the synthesis method,performance testing tips and related instruments’operation method for MOFs,but also combine theory with practice,connect basic knowledge with modern scientific research,and cultivate the students’chemistry research literacy.
