Abstract
Abstract Cerium oxide (CeO 2 ), 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 CeO 2 . The properties of CeO 2 are highly dependent on the synthesis conditions such as precursors, additives, calcination temperature and type of synthesis route. In this review article, synthesis of CeO 2 by various chemical routes are discussed in detail.
