Overview

Dual-site substitution improves hydrogen evolution performance in MoS2, indicating enhanced active site availability.

Key Points

  • To explore the dual-site substitution strategy for enhancing hydrogen evolution reaction activity in MoS2.
  • Substituted Mo and S in MoS2 with tellurium to create Te-MoS2.
  • Evaluated hydrogen evolution performance in acidic electrolyte.
  • Measured overpotential and current density during reactions.
  • Te-MoS2 requires an overpotential of 364 mV for 1000 mA·cm−2 current density.
  • Performance exceeds that of 20 wt% Pt/C, which has an overpotential of 506 mV.
  • Te-MoS2 retains activity for 200 hours without decay.
