Implication

Plasma engineering enhances oxygen evolution performance in perovskite catalysts, suggesting a pathway for efficient green hydrogen production.

Key Points

  • This work aims to enhance the oxygen evolution reaction (OER) activity of perovskite catalysts through plasma engineering.
  • Developed a plasma engineering strategy to modify LaMO3 perovskites (M = Fe, Co, Ni).
  • Characterized the modified catalyst V-LaFeO3 for specific surface area and oxygen vacancies.
  • Measured OER performance and overpotential at a current density of 10 mA cm-2.
  • V-LaFeO3 achieved a low overpotential of 332 mV at 10 mA cm-2.
  • Showed improved charge transfer capability and increased specific surface area compared to pristine LaFeO3.
  • Similar enhancements were observed in LaCoO3 and LaNiO3 after plasma treatment.
