Together with hydrotalcite-like layered double hydroxides, bivalent and trivalent metal hydroxides and their hydroxy salts are actually anionic clays consisting of positively charged hydroxide layers with anions intercalated in the interlayer region. The anionic clays exhibit anion sorption, anion diffusion and exchange properties together with surface basicity making them materials of importance for many modern applications. In this article, we discuss many different ways of making anionic… 
Oxidative leaching of chromium from layered double hydroxides: Mechanistic studies
The layered double hydroxide (LDH) of Zn with Cr on treatment with a hypochlorite solution releases chromate ions as a result of oxidative leaching by a dissolution-reprecipitation mechanism. The
High selectivity in anion exchange reactions of the anionic clay, cobalt hydroxynitrate
The selective uptake of fluoride ions from a mixture of halide ions and the selective uptake of chloride ions from a mixture of chloride, bromide and iodide ions were observed in the competitive


On the existence of hydrotalcite-like phases in the absence of trivalent cations
Abstract α-Hydroxides of nickel(II) and cobalt(II) are hydrotalcite-like phases, possessing a layered double hydroxide (LDH) structure even though there are no trivalent cations in the lattice. While
Comparative Study of Some Layered Hydroxide Salts Containing Exchangeable Interlayer Anions
Abstract Anion-exchange reactions of layered Zn, Cu, Ni, or La hydroxide nitrates with the organic anions acetate, terephthalate, and benzoate are compared. Powder X-ray diffraction (PXRD),
Intercalated Clay Catalysts
The intercalation of polynuclear hydroxy metal cations and metal cluster cations in smectites affords new pillared clay catalysts with pore sizes that can be made larger than those of conventional zeolite catalysts.
Synthesis, characterization and applications of layered double hydroxides containing organic guests
The use of layered inorganic solids as host materials for the creation of inorganic–organic host-guest supramolecular structures is of increasing interest. In this review we outline the preparation,
Ageing behaviour of unary hydroxides in trivalent metal salt solutions: Formation of layered double hydroxide (LDH)-like phases
The hydroxides of Mg, Ni, Cu and Zn transform into layered double hydroxide (LDH)-like phases on ageing in solutions of Al or Cr salts. This reaction is similar to acid leaching and proceeds by a
Organic Additive-Mediated Synthesis of Novel Cobalt(II) Hydroxides
Electrochemical precipitation of cobalt(II) hydroxide from nitrate solutions containing organic molecules, such as glucose, fructose, lactose, glycerol, and citric acid, yields a new modification of
Hybrid organic-inorganic layered compounds prepared by anion exchange reaction: correlation between structure and magnetic properties
The synthesis, structure and magnetic properties of a series of hybrid organic-inorganic copper(II) compounds are reported. Anion exchange reactions were used to prepare layered materials made of
