A systematic study on synthesis of CeO₂ nanoparticles by various routes

Abstract Cerium oxide (CeO2), also known as, ceria, is a well-known n-type semiconductor material. It finds potential roles in various field applications such as catalysis, sensing and antibacterial. It is widely used as a photocatalyst for treatment of waste water pollutants, because of the variable oxidation state of cerium i.e. +3, and +4. Many reports are available in literature which deals with the synthesis and properties of CeO2. The properties of CeO2 are highly dependent on the synthesis conditions such as precursors, additives, calcination temperature and type of synthesis route. In this review article, synthesis of CeO2 by various chemical routes are discussed in detail.
