Comprehensive experiment on synthesis of zinc pyridine-2,6-dicarboxylate complex and preparation of nanometer zinc oxide by thermal decomposition
A comprehensive chemical experiment on the synthesis of zinc pyridine-2,6-dicarboxylate by room temperature solid state reaction and the preparation of nanometer zinc oxide by thermal decomposition of the complex was introduced.The zinc(II)complex was synthesized with zinc acetate and pyridine-2,6-dicarboxylic acid as raw materials.The composition and structure of the complex were characterized by EDTA titration,elemental analyses,single crystal X-ray diffraction,powder X-ray diffraction,infrared spectroscopy and thermogravimetric analysis.The nanometer zinc oxide was obtained by thermal decomposition using the zinc(II)complex as precursor and its particle size increases with the increase of pyrolysis temperature.The experiment involves the preparation of complex and nanomaterial,structural characterization,green chemistry concept and other knowledge,which is helpful to cultivate students' ability of comprehensive analysis and problem solving,and to enhance students' scientific thinking and innovation ability.
