B, N-doped molybdenum disulfide for electrocatalytic study of oxygen reduction reaction

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.
