| ملخص فكرة المشروع | Layered double hydroxides (LDHs), also known as anionic clays or hydrotalcite (HT)-like materials, are a family of materials that have attracted increasing attention In Recent years. LDHs have anionic exchange capacity, and the ability to capture organic And inorganic anions makes them almost unique as inorganic materials. This review presents the wide variety of methods that are available for the synthesis of LDHs and focus on the way In which the physicochemical properties of the materials vary with synthesis method. <br /> Also deals with the characterizations of LDHs and applications of LDHs In removal of heavy metals from water with different methods. This review aims to revise literature about the different types of LDHs and reach a conclusion of Its benefits and how to use it.Layered double hydroxides (LDHs), are a class of synthetic two-dimensional nanostructured anionic clays, characterized by there unique lamellar structure which consist of positively charged metal hydroxide layers intercalated with anions and water molecules, whose structure can be described as containing brucite-like layers, where a fraction of the divalent cations coordinated octahedrally by hydroxyl groups have been replaced isomorphously by trivalent cations, giving positively charged layers with charge-balancing anions between them. Their general formula is [M²⁺₁₋ₓM³⁺ₓ(OH)₂]ˣ⁺[Aⁿ⁻]ₓ/ₙ·mH₂O, where M²⁺ and M³⁺ are divalent and trivalent metal cations, respectively, and Aⁿ⁻ represents the interlayer anions.A large<br /> class of isostructural materials, which can be considered complementary to aluminosilicate clays, with widely varied physicochemical properties can be obtained by changing the nature of the metal cations, the molar ratios, as well as the type of interlayer anions.<br /> LDHs, both as directly prepared or after thermal treatment, are promising materials for a large number of practical applications in catalysis, adsorption, pharmaceutics, photochemistry, electrochemistry and other areas. This is due to their high versatility, easily tailored properties and low cost, which make it possible to produce materials designed to fulfil specific requirements. |
