Cu/g-C_(3)N_(4)光催化氧化硫醚实验教学设计与实践

Experiment Design and Teaching Practice of Cu/g-C_(3)N_(4) as Photocatalyst for Oxidation of Thioether

为提高无机化学专业学生综合实验能力,设计新型实用的光催化氧化硫醚实验代替传统的光降解实验,符合可持续化学和本科生实验教学发展要求。本实验设计包含铜/氮化碳光催化剂的制备及光催化氧化硫醚反应的研究,同时设计了光催化剂的形貌和结构表征及产物的定性及定量分析等实验内容。提升学生对光催化材料的制备及表征技术、掌握气相色谱仪等仪器的实验方法,学会分析表征结果和实验数据等相关知识。本实验涉及光催化技术和绿色化学科学热点,可以拓宽学生视野,激发学生对实验和科学研究的兴趣,为提升本科生无机化学实验教学奠定扎实的基础。

In order to improve the comprehensive experimental ability of students majoring in Inorganic Chemistry,a new practical photocatalytic oxidation of sulfide experiment was designed to replace the traditional photodegradation experiment,which met the requirements of sustainable chemistry and undergraduate experimental teaching development.The preparation of copper/carbon nitride photocatalyst and the study of photocatalytic oxidation of sulfide reaction were included.At the same time,the morphology and structure characterization of the photocatalyst and the qualitative and quantitative analysis of the product were designed,which can improve students knowledge of the preparation and characterization of photocatalytic materials,master the experimental methods of instruments such as gas chromatographs,and learn to analyze characterization results and experimental data.The photocatalytic technology and green chemistry science hotspots were involved,which can broaden students horizons,stimulate students interest in experiments and scientific research,and a solid foundation was laid for improving undergraduate Inorganic Chemistry experiment teaching.
