Amorphous <i>versus</i> nanocrystalline RuO<sub>2</sub> electrocatalysts: activity and stability for oxygen evolution reaction in sulfuric acid
Kosuke Beppu, Kazuki Obigane, Fumiaki Amano
Abstract
Amorphous RuO 2 have high OER activity but are unstable during the OER in 0.1M H 2 SO 4 . RuO 2 nanoparticles with high crystallinity simultaneously achieved high OER activity and stability.
