Abstract
Layered double hydroxides (LDHs) are a class of materials with useful properties associated with their anion exchange abilities for a wide range of materials’ applications including adsorbent, catalyst and its support, ceramic precursor, and drug carrier. In order to satisfy the requirements for the detailed characterization and the practical application, the preparation of LDHs with varied composition and particle morphology has been examined extensively. The versatility of the preparation methods led LDHs with varied composition and micro/macroscopic morphology, which makes the application of LDHs more realistic. In the present review article, synthetic methods of LDHs are overviewed in order to highlight the present status of the LDHs for practical application.
Highlights
Layered double hydroxides (LDHs) are one of layered materials whose structure is composed of brucite (Mg(OH2)) like layers stacked with interlayer anion
We have revealed the successful control of the particle size distribution using the hydrothermal reaction in aqueous alcohol [108,109]
The preparation of layered double hydroxides was summarized with the emphasis on the chemistry in the formation of layered double hydroxides
Summary
Layered double hydroxides (LDHs) are one of layered materials whose structure is composed of brucite (Mg(OH2)) like layers stacked with interlayer anion. In order to optimize materials’ performances, efforts have been made to vary the composition as well as the particle morphology of the LDHs and their intercalates. Rheology of LDH suspension, which has been studied for the application as paints and for the preparation of polymer nanocomposites, is affected by the particle size [38,39,40]. Fabrication of LDH films has been investigated for electrochemical and photochemical applications [41,42,43,44,45,46]. These nanoscopic particle morphologies and micro/meso/macroscopic hierarchical architectures have been designed based on the sophisticated synthetic strategy and careful optimization of the reaction conditions.
