Recent progress in polyoxometalate-intercalated layered double hydroxides composite materials

Abstract

Layered double hydroxides (LDHs) or hydrotalcite-like compounds are an important large family of two-dimensional (2D) anionic clay materials which possesses flexible tunability, uniform distribution of metal cations in the layers, and the facile exchangeability of intercalated anions. Polyoxometalates (POMs) are a class of V, Mo, and W-containing discrete anionic metal oxides that can be viewed as transferable building blocks. Owing to the modular accessible gallery and unique inter-lamellar chemical environment, the POMs intercalated LDHs have shown wide application in environment, energy, catalysis, etc . This review mainly focuses on the summary of synthetic strategy and recent development of the POM/LDHs composite materials.
