How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the broader family of oxygen-evolution catalysts, NiCO2 occupies a distinct niche compared to well-characterized materials like NiO or LiCoO2. While many of its siblings, such as LaNiO3 or LiMn2O4, are known for their metallic or semi-metallic behavior and high conductivity, NiCO2 remains an insulating phase, making it a specialized subject for studies focusing on the impact of electronic structure on catalytic activity.
