摘要：

以Cu-MOF为前驱体，通过热解法制备氮掺杂多孔碳包覆铜纳米材料，采用X射线粉末衍射仪(XRD)、场发射扫描电子显微镜(SEM)和傅立叶变换红外光谱仪(IR)等仪器对产物的形貌和组成进行表征。考察了不同热解温度对多孔碳材料形貌和组成的影响，探究其在硝基苯还原反应中的催化性能，并优化了反应条件。将材料的制备、表征和性能探究设计成一个综合实验，能够培养学生的科研思维和综合分析能力。

Abstract:

Cu nanoparticles (NPs) supported on nitrogen-doped porous carbon (NPC) were synthesized by pyrolysis of Cu-metal organic frameworks (MOF) and characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and infrared spectroscopy (IR) to investigate their morphology and composition. In addition, the catalytic performance for the hydrogenation of nitrobenzene was explored and the catalytic reaction conditions were optimized. The methodical experimental procedure was designed in a comprehensive manner to cultivate scientific thinking and enhance the overall analytical skills of students.

Key words: N-doped porous carbon, MOF-derived materials, Catalytic hydrogenation, Comprehensive experiment
