摘　　要：Cerium-based materials are widely used in various applications such as photocatalytic environmental remediation,CO_(2)photoreduction and photocatalytic hydrogen production due to their unique optical properties and special oxygen vacancy formation mechanisms.The special external electronic structure of cerium(4f^(1)5d^(1)6s^(2)),the highly electronic 4f orbital,promotes the formation of oxygen vacancies through Ce^(4+)/Ce^(3+)conversion,thereby improving the optical properties of the catalyst.Consequently,the application of cerium-based materials in the field of photocatalysis has been of great interest to researchers.In this paper,we briefly review the synthesis of cerium-based photocatalysts and their applications in pollutant removal,CO_(2)reduction,and hydrogen production,as well as their promising applications.
