Some Applications of CeO2 Nanoparticles

Abstract

Various properties of cerium oxide (Ceria, CeO2) have been widely used in recent times. This article aims at discussing some fundamental properties of ceria, its application due to oxygen vacancies in its structure, its effects due to nano-size, synthesis strategy to give it a structure with diverse applications. Some basic applications of ceria-based structure have been reviewed. Ceria nanoparticles are used in catalytic converters in the automotive industries to convert harmful carbon monoxide to less harmful carbon dioxide, semiconductor industries uses it as fine abrasive and polishing agent, it can light production in mantles of gas lanterns where cerium oxide generates a yellowish white colour. Certain probable toxic effects and challenges in controllable synthesis of nanomaterials for its applications have been reviewed.
