摘　　要：介绍了一个由科研工作转化来的综合化学新实验。采用浸渍还原法制备Pt/C纳米催化剂,用XRD、TEM表征催化剂的结构和形貌,通过循环伏安(CV)、线性扫描伏安(LSV)曲线对温度、H2O2浓度的影响做了研究。实验要求学生掌握催化剂的表征及电极反应测试技术,学会根据实验数据和文献对各种影响因素进行分析与探讨。实验内容的设置有利于培养学生的创新和科研能力。The method for preparation of Pt/C nano - particle catalyst by impregnation chemical reduction reaction was introduced as a new comprehensive chemistry experiment. The catalyst＇ structure and morphology were characterized by XRD and TEM techniques. The effects of temperature and H2O2 concentration on the performance of Pt/C catalytic reduction H2O2 were studied by cyclic voltammetry and linear sweep voltammetry curves. Students were required to master catalyst characterization and testing techniques. The various influencing factors were analyzed according to the experiment data and literatures. The experiment was helpful to develop students＇ creative and practical ability.
