Available in PDF, EPUB and Kindle. Book excerpt: Layered double hydroxides (LDHs) are clay-type materials with extraordinary properties, whose structure is composed of stacked inorganic metal oxide layers built by connected sheets. The crystal structure of layered double hydroxides is based on positive charged brucite-like mainlayers and balanced by reversible exchangeable interlayer anions, additional cations and water molecules. Due to their negligible toxicity and buffering properties, LDHs are commercially employed as antacids and they are increasingly studied as vehicles in drug and gene delivery systems. This book discusses the synthesis, characterization and applications of layered double hydroxides.

Book excerpt: Layered double hydroxides are one of the variety of names given to a family of layered materials first discovered in Sweden in 1842. These materials are interesting because their layer cations can be changed among a wide selection, and the interlayer anion can also be (nearly) freely chosen. Like cationic clays, they can be pillared and can exchange interlayer species -- thus increasing applications and making new routes to derivatives. The principle areas of application include catalyst support, anion scavengers, polymer stabilisers, and antacids. In the last several years, reviews and studies of LDHs have dealt with these uses. This book aims to update the current body of LDH knowledge from a wide array of views. The first section addresses the synthesis and physiochemical characterisation of these materials, and section two focuses on the applications of LDHs.

Available in PDF, EPUB and Kindle. Book excerpt: Very few materials have attracted so much attention in recent years, both from researchers and industry, as layered double hydroxides (LDHs) have. LDHs, which are also referred to as anionic clays or hydrotalcites, are a wide class of inorganic ionic lamellar clay materials consisting of alternately stacked positively charged metal hydroxide layers with intercalated charge-balancing anions in hydrated interlayer regions. Their unique properties, such as their extremely high versatility in chemical composition and intercalation ability, extraordinary tuneability in composition as well as morphology, good biocompatibility and high anion exchangeability, have triggered immense interdisciplinary interest for their use in many different fields of chemistry, biology, medicine, and physics. Indeed, the applications of LDHs are constantly growing: LDHs, in the form of aggregated lamellar clusters, exfoliated single-layer nanosheets, or hierarchical films of interconnected nanoplatelets, can be effectively used as nanoscale vehicles in drug delivery, heterogeneous catalysts and supports for molecular catalysts, ion exchangers and adsorbents, solid electrolytes or fillers in electrochemistry, for the fabrication of superhydrophobic surfaces, water treatment and purification, and the synthesis of functional thin films. This book gathers the contributions to the Special Issue “Layered Double Hydroxides” of Crystals, which includes two review articles and seven research papers.

Available in PDF, EPUB and Kindle. Book excerpt: Layered Double Hydroxides (LDHs) certainly do not represent a newcomer to the scientific community, yet they continue to attract a strong and general interest among a vast and multifaceted range of researchers. This persistent modernity is definitely due to some peculiar characteristics of these materials, which allow researchers and engineers to play with different aspects of two worlds: organic and inorganic, crystalline and molecular, solid and liquid, cationic and anionic. A virtually infinite number of possible chemical combinations takes advantage of their layered structure to express an unrivaled collection of remarkable properties. The capture and/or release of organic and inorganic species, versatile low-cost catalytic activity, and blending with other compounds to build up a variety of hybrid composites, are just some of the many effects investigated to date. As a result, the applications encompass almost all aspects of our life, ranging from renewable energy production to water purification, including biomedical applications, gas sensing, drug delivery, and food packaging and safety. This Special Issue highlights some of the recent research lines, and shows that remarkable progress has been and is still being made in all these aspects, to allow the consideration of LDHs as one of the most interesting and versatile inorganic 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"--

This book was released on 2016-07-15 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a combination of material synthesis and characterization with process modeling. In it, the CO2 adsorption properties of hydrotalcites are enhanced through the production of novel supported hybrids (carbon nanotubes and graphene oxide) and the promotion with alkali metals. Hydrogen is regarded as a sustainable energy carrier, since the end users produce no carbon emissions. However, given that most of the hydrogen produced worldwide comes from fossil fuels, its potential as a carbon-free alternative depends on the ability to capture the carbon dioxide released during manufacture. Sorption-enhanced hydrogen production, in which CO2 is removed as it is formed, can make a major contribution to achieving this. The challenge is to find solid adsorbents with sufficient CO2 capacity that can work in the right temperature window over repeated adsorption-desorption cycles. The book presents a highly detailed characterization of the materials, together with an accurate measurement of their adsorption properties under dry conditions and in the presence of steam. It demonstrates that even small quantities of graphene oxide provide superior thermal stability to hydrotalcites due to their compatible layered structure, making them well suited as volume-efficient adsorbents for CO2. Lastly, it identifies suitable catalysts for the overall sorption-enhanced water gas shift process.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 summarise the current LDH potential applications and the possible future trends in agricultural, biological and medical researches (eg: 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.

This book was released on 2007-09-04 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The leaching of nitrate is an important way of N losses in crop production particularly during autumn and winter. Since nitrate as an anion is not adsorbed to the soil particles, it remains mobile in the soil. An efficient way to reduce nitrate leaching would be to control its movement in the soil by adsorbing it from the soil solution in the same way as clay minerals do it for cations like potassium and ammonium. The layered double hydroxide (LDH) minerals have anion exchange capacity, in contrast to the common soil clay minerals, which have cation exchange capacity. The LDH minerals are not often found in soils, but they can be synthesized at industrial scale. The present work evaluated the potential use of a specific LDH mineral as a long-term nitrate exchanger in the soil to adsorb nitrate if its concentration in the soil solution is higher than needed for optimal growth and to release it when the crop requires it. The LDH mineral acted as a long-term nitrate buffer in soil. The nitrate adsorbed on the mineral was efficiently protected against leaching, and was available for the crop. Also, the long-term stability as well as the structural changes of the LDH mineral under soil and cultivation conditions was investigated.
