How It Compares
Within the oxide oxygen-evolution catalysts class.
While common catalysts like NiO and LiCoO2 are widely utilized for their thermodynamic stability and well-understood behavior, Mg2Ni3O8 represents a more complex, metastable alternative. Unlike the perovskite-structured LaNiO3 or LaMnO3, which are frequently studied for their robust electronic conductivity, this magnesium-nickel oxide provides a different structural pathway for oxygen evolution that may offer unique surface reactivity.
