Comprehensive teaching experiment design on Cu nanoparticles embedded N-doped carbon as electrocatalysts for CO_(2)reduction

设计了一种Cu纳米颗粒嵌入N掺杂碳用于电催化CO_(2)还原的综合性教学实验,以常见的金属有机骨架材料为前驱体,通过煅烧制备两种Cu纳米颗粒嵌入N掺杂碳催化剂(Cu NPs/NC-1和Cu NPs/NC-2),并对制备的催化剂进行了TEM、XRD、XPS等形貌和组成测试,以及LSV、CV、阻抗等电化学测试,通过电流密度、起始还原电势、法拉第效率、Tafel斜率和电化学表面积等参数评价了两种催化剂的CO_(2)还原性能。

This paper illustrates a comprehensive teaching experiment design on Cu nanoparticles embedded N-doped carbon as electrocatalysts for CO_(2)reduction.Two kinds of Cu nanoparticles embedded N-doped carbon catalysts(Cu NPs/NC-1 and Cu NPs/NC-2)are prepared by calcination of common metal organic frameworks.The morphology and composition of the catalysts were characterized by TEM,XRD and XPS.LSV,CV and impedance are performed.Their performance of CO_(2)reduction was evaluated by current density,initial reduction potential,Faraday efficiency,Tafel slope and electrochemical surface area.
