How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the insulating or wide-gap semiconducting oxides such as NiO or BiFeO3, SrRuO3 functions as a semimetal, providing superior electrical conductivity that is essential for its performance as an electrode. While it shares the perovskite framework with materials like LaMnO3 and LaNiO3, its specific ruthenium-based chemistry offers distinct catalytic activity for oxygen evolution that differentiates it from the lithium-based transition metal oxides like LiCoO2 or LiMn2O4.
