How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the broader class of oxygen-evolution catalysts, CoSeO4 offers a distinct chemical environment compared to traditional transition metal oxides like NiO or LiCoO2. While many of its siblings are simple binary or layered oxides, the inclusion of the selenate group provides a unique structural framework that influences its catalytic activity and stability differently than the perovskite-structured LaMnO3 or LaNiO3.
