Cerium monoxide (CeO) is a rare-earth ceramic compound featuring cerium in the +2 oxidation state, belonging to the family of rare-earth oxides used in advanced functional materials. It is primarily explored in research and specialized applications where rare-earth ionic conductivity, optical properties, or catalytic function are required, including solid-state electrolytes, catalytic supports, and high-temperature structural components. CeO is less common industrially than cerium dioxide (CeO₂) but offers distinct properties relevant to emerging technologies in energy conversion and environmental remediation.
