Enhanced Electrocatalytic Performance of P-Doped MoS2/rGO Composites for Hydrogen Evolution Reactions
Wenjun Zhu, Bofeng Zhang, Yao Yang, Minghai Zhao, Yuwen Fang, Yang Cui, Jian TianThis study is based on the strategies of composite and element doping. Herein, P-MoS2/rGO materials were synthesized using a solvent-assisted hydrothermal method. The MoS2 nanosheets were uniformly and vertically grown on rGO; meanwhile, the optimized structure of MoS2 was achieved by P doping, resulting in improved catalytic performance and structural stability. Under alkaline conditions, the P-MoS2/rGO catalyst exhibits good electrocatalytic activity, demonstrating a Tafel slope of 70.7 mV dec−1 and an overpotential of 172.8 mV at 10 mA/cm2. Notably, even after 3000 consecutive LSV tests, the curves still show a high degree of overlap, indicating exceptional stability.
