硫化锰/碳材料的原位合成及赝电容性能探究——以综合化学实验为例

In-situ Synthesis and Pseudocapacitance of Manganese Sulfide/Carbon Materials——Take Comprehensive Chemical Experiment as An Example

以锰-六亚甲基四胺配位骨架为前驱体,采用简单的原位硫化法,制备了硫化锰/氮硫共掺杂碳纳米复合材料(MnS-NSC)。利用X射线衍射仪、扫描电镜等大型仪器进行材料的结构及形貌表征,利用电化学工作站进行电容器的电化学性能测试。该综合化学实验涵盖材料制备、表征及性能测试,体系完整,实用性强,涉及多种仪器使用,有助于从整体上培养学生的综合实验能力,提升科学研究素养和创新思维。

Manganese sulfide/nitrogen and sulfur co-doped carbon nanocomposites(MnS-NSC)were prepared by simple in-situ vulcanization method using Mn-hexamethylene tetramine coordination framework as precursor.The structure and morphology of the materials were analyzed by X-ray diffractometer and scanning electron microscope and so on.The electrochemical performance was tested by electrochemical workstation.The comprehensive chemical experiment has complete system and strong practicability,covering material preparation,characterization and performance testing,involving the use of a variety of large-scale instruments,which can cultivate students'comprehensive experimental ability as a whole,improve scientific research literacy and innovative thinking.
