Overview

Randomized trial shows enhanced activity and durability in proton exchange membrane water electrolyzers, suggesting improved catalyst design.

Key Points

  • The study aims to enhance the stability and activity of ruthenium oxide through boron doping via sonochemistry.
  • Cavitation-mediated sonochemical strategy used for homogeneous boron doping of ruthenium oxide.
  • Assessment of overpotential and durability of the boron-doped catalyst in acidic water electrolysis.
  • Evaluation of catalyst performance under industrial current densities.
  • Boron-doped ruthenium oxide exhibits a low overpotential of 180 mV at 10 mA cm−2.
  • Shows long-term durability (>3000 hours) and operates at 1 A cm−2 for over 200 hours at 1.714 V.
  • Demonstrates a negligible voltage degradation rate of 65.0 μV h−1.
