Application

Cerium Oxide serves as a versatile catalyst and substrate known for its high monodispersity in size and shape, ensuring a polydispersity index of less than 0.25, which significantly enhances surface reactivity. Its stability at high suspension densities within a recommended pH range makes it a preferred choice in various industrial applications. Notably, it plays a crucial role in emissions catalysis and is an effective electrolyte for fuel cells. Its polishing properties are vital for optical surfaces and semiconductor planarization. Additionally, Cerium Oxide acts as a substrate for precious metals in oxidation catalysis and is integral in catalyzing water splitting for hydrogen production. Beyond these, it also functions as a radical oxygen scavenger in biological systems.
