Overview

Ge doping improves overpotential and stability in acidic oxygen evolution reaction electrocatalysts, suggesting better performance.

Key Points

  • The optimized germanium-doped RuO2 shows an ultralow overpotential of 161 mV at 10 mA cm−2, and a stability of 650 h at 100 mA cm−2.
  • Key findings include a decay rate of 0.164 mV h−1 during long-term testing, indicating effective performance retention over time.
  • In situ spectroscopy techniques reveal that Ge doping facilitates water dissociation and enhances catalytic activity via structural stability improvements.
  • This research highlights the potential of non-metallic doping strategies in designing robust electrocatalysts for acidic water splitting.
