Used as a precursor in the synthesis of cerium oxide (CeO₂) nanoparticles, which are essential in catalytic converters for reducing automotive emissions. Employed in the preparation of catalysts for organic reactions due to cerium’s redox properties. Applied in glass and ceramic industries to improve UV absorption and provide decolorizing effects. Utilized in coating materials to enhance corrosion resistance of metals. Serves as a dopant in phosphors and luminescent materials for lighting and display technologies. Also used in research for developing solid oxide fuel cells and other energy-related materials.
