醇试剂下NMV杂多酸的快速合成及其电化学性能综合实验教学设计

Instructional Design for Comprehensive Experiment of Rapid Synthesis and Electrochemical Properties of NMV POMs with Alcohol Reagent

为了达成工程教育专业认证对学生实践能力的培养要求,在能源化工专业实验中设计了“NMV杂多酸的快速合成及其电化学性能”综合实验。实验内容包括NMV杂多酸的快速合成、结构表征及电化学性能测试等内容。要求学生通过文献查阅了解NMV的合成方法和条件,设计NMV的合成方案,掌握电子显微镜、扫描电镜、X射线衍射、单晶X射线衍射、X光电子能谱、热重等表征方法及NMV的电化学性能测试方法,分析总结实验数据。此外,建立了兼顾过程和结果的考核体系,通过实验方案设计、实验过程操作与实验报告撰写等环节全面考查学生的综合实践能力。该实验教学设计体现了学生的主体地位,提高了学生的动手能力、思考能力和实践能力,也培养了学生的创新思维。

In order to meet the requirements of engineering certification education for the cultivation of students'practical ability,a comprehensive experiment of“rapid synthesis and electrochemical performance of NMV polyoxometalates(POMs)under alcohol reagent”was designed in the experiment of energy and chemical engineering specialty.The experimental contents include the rapid synthesis,structural characterization and electrochemical performance test of NMV POMs.Students are required to understand the synthesis process and conditions of NMV POMs through literature review,design the synthesis scheme of NMV POMs,master the characterization methods such as X-ray diffraction,X-ray single crystal diffraction,thermogravimetry and the electrochemical performance test methods of NMV,and analyze and summarize the experimental data.In addition,an assessment system that takes into account both the process and the results is established to comprehensively examine the students'comprehensive practical ability through the links of experimental scheme design,experimental process operation and experimental report writing.The experimental teaching design reflects the dominant position of students.Through this teaching practice,students'practical ability,thinking ability and practical ability are not only improved,but also their innovative thinking is cultivated.
