How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse class of oxygen-evolution catalysts, YMn2O5 occupies a distinct niche compared to more common spinel structures like LiMn2O4 or layered oxides such as LiCoO2. While many members of this class are optimized for lithium-ion battery electrodes, YMn2O5 is specifically noted for its structural stability and semiconducting nature, which differentiates it from the highly conductive metallic-like behavior found in perovskites such as LaNiO3.
