Implication

Self-supported heterojunction catalysts exhibit low overpotentials for oxygen and hydrogen evolution, suggesting enhanced efficiency.

Key Points

  • The electrocatalyst requires only low overpotentials of 263 and 173 mV for oxygen and hydrogen evolution, respectively.
  • Excellent stability for 300 and 150 hours was observed during the oxygen and hydrogen evolution reactions in KOH solution.
  • In situ techniques showed that Fe doping improved electron transport efficiency, enhancing overall catalytic activity.
  • The electrocatalyst achieves high performance in simulated seawater, demonstrating versatility and practical application.
