中文摘要: |
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-MoS2)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,测试结果表明,制备的B, N-MoS2材料提高了ORR电催化活性与稳定性,而且是一个近4 e-的路径。本工作为进一步深入研究燃料电池阴极氧还原催化性能的提高奠定了基础。 |

For the cathodic reaction of alkaline fuel cells, it is very important to develop new catalysts with excellent catalytic performance. In this work, a simple pyrolysis method was used to synthesize boron and nitrogen-doped molybdenum disulfide (B, N-MoS2) catalysts and for the electrocatalytic analysis of oxygen reduction reaction (ORR). The catalytic activity of the B, N-MoS2 catalyst was measured by cyclic voltammetry (CV), linear sweep voltammetry (LSV), rotating disk electrode (RDE) and rotating ring disk electrode (RRDE). The results showed that the prepared B, N-MoS2 catalyst enhanced the catalytic activity and stability of ORR. And it"s a path that"s close to 4 e-. This work lays a foundation for further study on improving the catalytic performance of oxygen reduction reaction. |
