Layered double hydroxides (LDHs) are anionic clays, and the general formula for LDHs is [MII1－x MIIIx(OH)2][(An－)x/n・mH2O], where MII is a divalent cation, and MIII is a trivalent cation, and An－ is an anion. LDHs consist of alternately stacked layers of the positively charged metal hydroxide nanosheets (charged layers) and interlayer anions with binding field. In hydroxide nanosheets, metal ions with different valence are self-assembled in-plane. These periodic structures are formed under the ambient atmosphere. Over the last decade, research on LDHs has been developing in several fields and applications, in both fundamental and applied aspects of these materials. However, communication between researchers on LDHs with different research fields is insufficient. Collaboration of researchers under the concept of science and design binding field with charged layers must lead to significant developments in hydroxide-based materials with layered structure.
This symposium will focus on preparation, characterization, application, and novel properties of LDHs, layered hydroxides, and hydroxide nano-sheets in any research field. The science and design of “binding field with charged layers” will be discussed.
