Removal of radionuclides by layered double hydroxides materials

Layered double hydroxides(LDHs),one of the most important two-dimensional layered compounds,have enabled massive developments in effective pollution treatments.Over the past few decades,their derivative materials have also applied to the efficient removal of radionuclides owing to the intrinsic advantages of their low cost,easy preparation,large surface areas,topological transformation,and environment-friendly.In this review,we give an overview of the recent advances in LDH-based nanomaterials,from a brief introduction to their preparation and modification methods to an overview of their application in the removal of radionuclides and an exploration of their underlying adsorption mechanisms.In the end,a summary and outlook are also briefly addressed.This review intends to provide deep insight into the design of high-performance LDH-based materials for the potential elimination of radionuclides from aqueous solutions during environmental pollution cleanup.
