How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the well-established binary oxide NiO or the layered lithium-intercalation compounds like LiCoO2 and LiNiO2, NiSeO4 introduces the selenate anion into the catalytic framework. While perovskite-structured members such as LaNiO3 and LaMnO3 are widely recognized for their robust performance in oxygen-evolution reactions, NiSeO4 offers a distinct chemical environment that differentiates it from the simpler transition metal oxides and complex perovskites like BiFeO3 or La2NiO4.
