Underwater Plasma Synthesis of Zn–Al Layered Double Hydroxides

Abstract— Layered double hydroxides containing zinc in the doubly charged cation position and aluminum in the triply charged cation position of brucite-like structures have been synthesized by a new method with the use of a low-temperature underwater plasma. Electrode materials were used as precursors. Well-crystallized layered double hydroxides and impurity phases have been obtained. The thermal stability of the materials has been shown to be due to the presence of impurity phases. The synthesized layered structures have a large specific surface area, which allows them to be used as fillers for polymer-matrix composites.
