| 摘 要： | 本文采用原位合成法制备了钌/氮掺杂石墨烯(Ru/NGR)催化剂,并采用X射线衍射(XRD)、X射线光电子能谱(XPS)、透射电子显微镜(TEM)等手段对催化剂的结构形貌进行了表征。将Ru/NGR催化剂应用于硼氢化钠水解制氢体系,考察了钌的负载量、硼氢化钠的浓度、反应温度等对硼氢化钠产氢的催化性能的影响。研究结果表明:当温度为25℃,硼氢化钠浓度为2 wt%,钌负载量为3.9%时,产氢速率可达32.95 L·(gRu·min)^-1。通过对Ru/NGR催化剂催化硼氢化钠水解反应动力学数据研究研究得出该催化剂的活化能为46 kJ·mol^-1。

| Abstract: | Ruthenium/nitrogen doped graphene(Ru/NGR)catalyst was prepared by in situ synthesis method.The structure of the catalyst was characterized by X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS)and transmission electron microscope(TEM).Ru/NGR catalyst was applied to the hydrogen production system of sodium borohydride and the effects of content of ruthenium,concentration of sodium borohydride and reaction temperature on the catalytic performance of sodium borohydride for hydrogen production were studied.The results showed that the temperature 25℃,the concentration of sodium borohydride 2 wt%,and the content of ruthenium 3.9%,hydrogen production rate reached 32.95 L·(gRu·min)^-1.The kinetic data showed that the activation energy of Ru/NGR catalyst for hydrolysis of sodium borohydride was 46 kJ·mol^-1. |
