How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the broad class of oxygen-evolution catalysts, K2CoO3 stands out as a metastable alternative to more conventional, highly stable materials like LiCoO2 or LaMnO3. While many of its class members, such as NiO or LiMn2O4, are recognized for their robust structural integrity, K2CoO3 provides a different electronic landscape that researchers explore to overcome limitations inherent in more common perovskite or spinel-based catalysts.
