Book Description
Layered double hydroxides (LDHs) or hydrotalcites are inorganic clay materials with many promising properties. LDHs are a family of natural and synthetic compounds having the general formula [M(II) 1-x M(III)x (OH)2 ](Yn-))x/n * yH2O, where M(II) and M(III) represent divalent and trivalent metal ions, respectively, and Yn- is the anion between the layers. They consist structurally of brucite-like [Mg(OH)2] layers, with a net positive charge due to partial substitution of M(II) by M(III). This positive charge is balanced by the anionic interlayer anion. Over the past few years, an increasing interest has been directed to the use of these clays as host materials, anion exchangers, delivery carriers and additives for polymers in order to create potential products with desirable physical and chemical properties. From the many significant research achievements and the many potential practical applications, it is assumed that the prospects for LDHs and their composites with the different organic and bioactive materials are very bright indeed and still more remains to be done in order to exploit completely their potential applications. In this book, we focus on the progress of the development of LDHs and their derivatives, including the synthetic techniques, the nanocomposite preparation routes, the factors affecting the physicochemical properties and how these properties affect the nanoparticle structure and the host-guest process. Furthermore, we summarize the current LDH potential applications and the possible future trends in agricultural, biological and medical researches e.g. the role of LDHs as reinforcements, as catalysts and catalyst supports in the field of catalysis, as a carrier in drug delivery and as host for a safe preservation of the bioactive material.

Book Description
Layered Double Hydroxides (LDH) are two-dimensional materials with unique physiochemical properties, which enable their use in a wide range of applications such as catalysis, biomaterials, energy, filler of polymeric composites, and water remediation.This book addresses basic aspects of LDH as the implementations in the methodologies based on density functional theory (DFT) to understand the properties and applications of LDHs, the synthetic methods to prepare LDHs and LDH based core-shell structures, and the swelling and exfoliation behaviors of LDH compounds. A relevant part of the book is devoted to consolidated and emerging applications of LDHs as catalysts in photocatalysis, electrocatalysis and water oxidation processes, as biomaterials and as functional fillers in food packaging. New advances on LDH are described with a keen eye on the past research.

Book Description
Ever since the discovery of graphene, two-dimensional layered materials (2DLMs) have been the central tool of the materials research community. The reason behind their importance is their superlative and unique electronic, optical, physical, chemical and mechanical properties in layered form rather than in bulk form. The 2DLMs have been applied to electronics, catalysis, energy, environment, and biomedical applications. The following topics are discussed in the book’s fifteen chapters: • The research status of the 2D metal-organic frameworks and the different techniques used to synthesize them. • 2D black phosphorus (BP) and its practical application in various fields. • Reviews the synthesis methods of MXenes and provides a detailed discussion of their structural characterization and physical, electrochemical and optical properties, as well as applications in catalysis, energy storage, environmental management, biomedicine, and gas sensing. • The carbon-based materials and their potential applications via the photocatalytic process using visible light irradiation. • 2D materials like graphene, TMDCs, few-layer phosphorene, MXene in layered form and their heterostructures. • The structure and applications of 2D perovskites. • The physical parameters of pristine layered materials, ZnO, transition metal dichalcogenides, and heterostructures of layered materials are discussed. • The coupling of graphitic carbon nitride with various metal sulfides and oxides to form efficient heterojunction for water purification. • The structural features, synthetic methods, properties, and different applications and properties of 2D zeolites. • The methods for synthesizing 2D hollow nanostructures are featured and their structural aspects and potential in medical and non-medical applications. • The characteristics and structural aspects of 2D layered double hydroxides (LDHs) and the various synthesis methods and role of LDH in non-medical applications as adsorbent, sensor, catalyst, etc. • The synthesis of graphene-based 2D layered materials synthesized by using top-down and bottom-up approaches where the main emphasis is on the hot-filament thermal chemical vapor deposition (HFTCVD) method. • The different properties of 2D h-BN and borophene and the various methods being used for the synthesis of 2D h-BN, along with their growth mechanism and transfer techniques. • The physical properties and current progress of various transition metal dichalcogenides (TMDC) based on photoactive materials for photoelectrochemical (PEC) hydrogen evolution reaction. • The state-of-the-art of 2D layered materials and associated devices, such as electronic, biosensing, optoelectronic, and energy storage applications.

Book Description
"Currently, Layered Double Hydroxides (LDH) is a hot area of research on inorganic layered materials. The present book, Applications of Layered Double Hydroxides, edited by Dr. Rjib Lochan Goswamee and Dr. Pinky Saikia, is a collection of articles from various researchers from different parts of the world mainly on structure and property relationships of various types of LDH and their related application prospects. How these application prospects can be related to the most pressing problems of humanity like drug delivery, global warming, green catalysis, electrochemical energy storage and generation etc. are clearly discussed in the articles inside. The book provides a thorough up-to-date review of recent literature on applications of LDH available in the global scientific and technical media. For example, the book lucidly describes the behaviour of LDH nanocarriers in biological fluids, their low cytotoxicity and high levels of cellular internalization, and high drug loading capacity. Similarly, the book examines why hybrid nanocomposites of LDH-MOF are considered promising materials due to their diverse functionality, flexible properties and tailored end-use properties. Likewise, application of LDH in secondary batteries and electro-chemical supercapacitors with a thorough up-to-date review is included in the book. Also, basic research articles on structural properties and measurements of a special class of unique LDH Li-Al-LDHs are included. Editors also have written their own articles on their findings on the prospective application of dispersions of LDH nanocomposites on structured catalysts for green-house gas emission. Overall, the book gives a short glimpse of wonderful opportunities that LDH can provide in solving many global socio-economic problems of today"--
