How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse family of oxygen-evolution catalysts, NiMoO4 distinguishes itself from conventional binary oxides like NiO by incorporating molybdenum to tune its electronic environment. While layered oxides such as LiCoO2 and LaNiO3 are frequently utilized for their intercalation properties, NiMoO4 provides a unique metallic framework that facilitates charge transfer, offering a distinct alternative to the perovskite-structured members of this class.
