Overview

In situ phase engineering improves hydrogen evolution reaction performance in electrocatalysts, indicating potential for efficiency gains.

Key Points

  • Electrocatalytic hydrogen evolution performance improved with a new electrocatalyst, achieving just 98 mV overpotential.
  • The optimized electrocatalyst demonstrated a favorable Tafel slope of 91 mV dec-1 at a current density of 10 mA cm-2.
  • Phase engineering with NiSe enhanced the catalytic activity of the MoS2 electrocatalyst via interface modulation.
  • Findings suggest that precise interface design can optimize hydrogen evolution reaction efficiencies.
