2021年2月4日 · Ruthenium-based catalyst is one of the most active catalysts for oxygen evolution reaction (OER) in acid media. However, the strong bonding between the Ru sites and oxygen intermediates leads to high overpotential to trigger the OER process.

2023年6月15日 · Ru has been demonstrated as one of the most potential catalysts for hydrogen evolution reaction because of its high activity and low price. The efficient Ru-based catalysts are normally achieved through controlled alloying, structure design, phase exploration, and carbon support modulation strategies.

Ruthenium dioxide (RuO 2) is one of the most promising acidic oxygen evolution reaction (OER) catalysts to replace the expensive and prevalent iridium (Ir)-based materials. However, the lattice oxygen oxidation induced Ru dissolution during OER compromises the activity and stability.
