| 摘 要： | 为提高催化剂的催化活性及稳定性,采用一步水热法合成二硫化钼/石墨烯(MoS 2/RGO)复合催化剂。利用X射线衍射仪、扫描电子显微镜、透射电子显微镜及旋转圆盘电极等分别对催化剂的物理-化学性能进行表征。结果表明:与石墨烯复合后,MoS 2呈少层花瓣状结构,层间距增加且均匀附着在石墨烯薄层上;二硫化钼催化剂的氧还原过程主要以二电子途径进行,而MoS 2/RGO复合催化剂在氧还原过程中可发挥协同催化作用,其氧还原过程中平均转移电子数为3.58,且复合催化剂在20000 s后的电流密度保持率高达89.7%。

| Abstract: | Molybdenum disulfide/reduced graphene(MoS 2/RGO)composite catalyst was synthesized by one-step hydrothermal method in order to improve the catalytic activity and stability.X-ray diffractometer,scanning electron microscope,transmission electron microscope and rotating disk electrode were used to characterize the physical and chemical properties of the catalyst.The results show that the molybdenum disulfide compound with graphene has pear-shaped structure with few layers,and the layer spacing increases which is uniformly attached to the thin layer of graphene.The oxygen reduction process of molybdenum disulfide catalyst is mainly carried out in two-electron path,while MoS 2/RGO composite catalyst can play a synergistic catalytic role in oxygen reduction process and the average number of electron transfer in the process is 3.58.The current density retention rate of the composite catalyst after 20000 s is up to 89.7%. |
