摘要
对于碱性燃料电池的阴极反应,开发具有优异催化性能的新型催化剂至关重要。本工作采用一种简单的热解方法合成了硼、氮掺杂的二硫化钼(B,N-MoS_(2))材料并将其应用于氧还原(ORR)电催化分析。通过循环伏安法(CV)与线性扫描伏安法(LSV)等电化学分析方法,采用旋转盘电极(RDE)与旋转环盘电极(RRDE)等技术测试了该材料的氧还原催化活性。结果表明,制备的B,N-MoS_(2)材料提高了ORR电催化活性与稳定性,而且是一个近4e^(-)的路径。本工作可为有关提高燃料电池阴极氧还原催化性能的研究提供参考。
For the cathodic reaction of alkaline fuel cells,it is very important to develop new catalysts with excellent catalytic performance.In this work,boron and nitrogen-doped molybdenum disulfide(B,N-MoS_(2))was synthesized by a simple pyrolysis method for the electrocatalytic analysis of oxygen reduction reaction(ORR).The catalytic activity of the B,N-MoS_(2)catalyst was measured by cyclic voltammetry(CV)and linear sweep voltammetry(LSV)using rotating disk electrode(RDE)and rotating ring disk electrode(RRDE).The results showed that the prepared B,N-MoS_(2)catalyst has enhanced catalytic activity and stability of ORR,and the catalysis is a path close to 4 e^(-).This work can provide a reference for the research on improving the catalytic performance of oxygen reduction reaction.
