How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse family of oxide oxygen-evolution catalysts, CaNiO3 occupies a distinct niche compared to more conventional materials like NiO or the layered LiNiO2. While many of its siblings, such as LaNiO3, exhibit robust stability, the metastable character of CaNiO3 offers a different pathway for surface reactivity that is not present in more thermodynamically stable perovskites like LaMnO3.
