How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse landscape of oxygen-evolution catalysts, CaFeO3 distinguishes itself through its semimetallic nature, contrasting with the more insulating behavior often found in oxides like NiO. While complex layered systems such as La2NiO4 or LiCoO2 are frequently explored for their ionic mobility, CaFeO3 offers a unique electronic profile that bridges the gap between simple binary oxides and more intricate perovskite-based catalysts like LaMnO3.
