Overview

Randomized trial shows enhanced oxygen evolution in electrocatalysts, indicating improved energy conversion efficiency.

Key Points

  • The study aims to develop efficient iridium single-atom catalysts for acidic oxygen evolution and understand the impact of coordination structures.
  • Developed single-atom Ir catalysts on polyimide support for OER.
  • Investigated two coordination structures: Ir-N2O2 and Ir-C2O2 for activity comparison.
  • Conducted both experimental and theoretical analyses to evaluate performance and mechanisms.
  • Ir-N2O2 coordination achieved a low overpotential of 198 mV at 10 mA cm−2 with no activity decay over 500 hours.
  • Ir-N2O2 significantly reduced the thermodynamic barrier for *OOH adsorption compared to Ir-C2O2.
  • Enhanced proton-electron transfer kinetics were observed at the Ir-N2O2 site due to better charge delocalization.
