Layered Double Hydroxides and their Use as Catalysts in Fine Chemicals

Layered Double Hydroxides (LDH) are a class of anionic clays whose structure is based on the brucite, Mg(OH)2, in which some of the divalent cations are replaced by trivalent cations, thus generating a positive charge in the layer. This charge is balanced by the presence of an anion located in the interlayer space. Due to some amazing properties (such as high ion exchange capacity, modification of the inter-lamellar space depending on the embedded anion, uniform dispersion of cations in the network, memory effect, etc.) these materials are viable catalysts in various chemical reactions. The synthesis of these materials is simple and is done through a large number of preparation methods, both at laboratory and industrial scales. Due to the fact that these materials have acid-base properties, they can be successfully used as catalysts in fine chemicals.

This Research Topic aims to highlight and promote research on the preparation methods of LDH- type materials, their characterization by several techniques and their application in new reactions or on improving existing ones in the field of fine chemicals. Operando spectroscopy is also accepted.

We invite the submission of Original Research, Review, Mini Review, Perspective articles on themes including, but not limited to:

• Layered Double Hydroxides
• LDH as catalysts and support
