Recent advances on polyoxometalates intercalated layered double hydroxides: From synthetic approaches to functional material applications

Abstract Polyoxometalates (POMs) exhibit attractive properties and great potential to meet with contemporary society demands regarding environment, materials, energy, health and information technologies, etc. The development of POM-based advanced functional materials is of significance to effectively utilize POMs in meeting various challenges. In recent years, the intercalation of POM anions into layered double hydroxides (LDHs) has been a versatile and important approach for the development of POM-based multifunctional materials. The current review summarizes the latest progress on the preparation of POM intercalated LDHs (denoted as POM/LDHs) and their material application.
