摘要
由"溶液吸附法测定硅胶比表面"实验出发,结合目前的科研热点,设计了一个研究型的综合化学实验,即氮、硫共掺杂的功能化碳催化剂的制备、表征及催化活性评价。学生通过实验将掌握绿色化学基本原则、实验室废弃物综合利用、热分析法测定材料的稳定性、催化剂活性评价等相关理论和实验技能。此外,学生还可以掌握科研过程中广泛应用的材料表征方法,例如X射线粉末衍射、X射线光电子能谱、透射电子显微镜、扫描电子显微镜等。实践表明,在实验教学中引入科研热点,有助于激发学生的创新思维,对学生的科研能力和科学素养的培养具有事半功倍的效果。
A research comprehensive chemical experiment,namely"preparation,characterization and catalytic activity evaluation of N/S co-doped carbon materials",was designed.This experiment was derived from a normal teaching experiment,"determining specific surface area of silica gel by solution adsorption".And the current research hotspots were also introduced into the experiment.Through this new comprehensive experiment,we improved the students'theoretical knowledge and experimental skills,such as the basic theory of green chemistry,comprehensive utilization of laboratory wastes,determination of the stability of materials by thermal analysis,evaluation of catalyst activity.In addition,students could grasp the material characterization methods widely applied in scientific research,such as X ray powder diffraction,X ray photoelectron spectroscopy,transmission electron microscopy,scanning electron microscope and so on.The practice has shown that the introduction of research frontier into experimental teaching is beneficial for stimulating student's innovative thinking and is helpful to improve students'scientific research ability and scientific literacy.
