摘要
为了开拓学生的科学眼界,加深学生对于催化剂以及电催化反应的理解,设计开发了基于金属-有机框架物(metal-organic frameworks,MOF)衍生NiSe_(2)的制备及电催化析氢的综合性实验。实验制备MOF纳米片作为前驱体,进一步二次煅烧制备核壳结构的NiSe_(2)@NC催化剂,通过X-射线粉末衍射(powerx-raydiffraction,PXRD)、X射线光电子能谱(X-ray photoelectron spectroscopy,XPS)和透射电子显微镜(transmission electron microscope,TEM)等分析手段对产品进行表征,最后考察材料的电催化析氢性能。通过该综合实验,学生不仅可以了解相关科技前沿,而且可以更好地掌握MOF及其衍生催化剂的合成方法、电催化性能测试以及电化学工作站等仪器的使用操作技能,为将来从事相关科研或实践工作打下基础。
In order to broaden students′scientific horizons and deepen their understanding of catalysts and electrocatalytic reactions,a comprehensive experiment based on the preparation of metal-organic framework(MOF)derived NiSe_(2)and electrocatalytic hydrogen evolution is designed.In the experiment,the core-shell structure NiSe_(2)@NC catalyst is obtained by preparing MOF nanosheets as the precursor and further secondary calcination.Power X-ray diffraction(PXRD),X-ray photoelectron spectroscopy(XPS),transmission electron microscope(TEM)and other analytical methods are used to characterize the product,and finally the electrocatalytic hydrogen evolution performance of the material is investigated.Through this experiment,students can not only understand the relevant frontiers of science and technology,but also better master the synthesis methods of MOF and its derivative catalysts,the performance test of electrocatalytic reactions,and the operation skills of electrochemical workstations and other instruments,laying a foundation for the ralated scientific research or practical work in the future.
