How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse group of oxygen-evolution catalysts, RbCoO2 occupies a specialized niche compared to well-established materials like LiCoO2. While LiCoO2 is a cornerstone of battery technology, RbCoO2 offers a different structural framework due to the larger rubidium cation, which influences the cobalt-oxygen coordination environment and potential catalytic pathways relative to other complex oxides like LaMnO3 or BiFeO3.
