摘要
设计了一个与科研工作紧密相关的综合性实验。通过硬模板法和催化自生长法制备含钴碳纳米管原位嵌入的复合型反蛋白石结构,利用SEM、TEM、XRD、XPS等对催化剂的形貌结构进行表征,并采用线性扫描伏安、塔菲尔曲线等手段对其氧还原电催化活性进行评价。本实验的开展及文献调研,将提高学生对电催化相关新能源材料与设备的认识,发展学生对组分-结构-性能关系的科学思维与认知。
A comprehensive experiment closely related to scientific research was designed.A composite of cobalt-containing carbon nanotubes in-situ embedded inverse opal structure was prepared by hard template method and catalytic self-growth method.The structure and components of the catalyst were characterized by SEM,TEM,XRD,XPS,etc.The electrocatalytic activity of oxygen reduction reaction was evaluated by linear sweep voltammetry,Tafel curve and other means.The development of this experiment and related literature research would improve the students understanding of new energy materials and electrocatalysis related equipment,and develop the students scientific thinking and cognition of the relationship between component-structure-performance.
