“…Several studies showed the interest of immobilizing heme proteins, particularly hemoglobin (Hb), on LDH or LDH-containing nanocomposite supports to fabricate biosensors based on the direct electrochemistry of redox protein. These bioelectrodes have low detection limit and very high sensitivity for the amperometric detection of H2O2 or high activity for the electrocatalytic reduction to trichloroacetic acid for example [131][132][133][134]. Among LDH matrices, the Fecontaining ones have a peculiar interest as they promote direct electron transfer between heme proteins and the underlying electrode, iron atoms acting as electron relays [131].…”

“…[39][40] The room temperature conductivities, for ionic liquids based on ammonium cations, are in the range between 0.1 and 5 mS cm À1 . [42][43][44][45][46][47][48][49][50][51][52] The application of LDHs as hydroxide ion conducting electrolytes in alkaline fuel cells was already reported; [32,53] MgÀAl layered double hydroxides containing glycine betaine as an IL showed good performances as electrolyte material for solid state alkaline fuel cells. In spite of these potential advantages, only few studies have been carried out so far on LDH-ILs, which can be used for catalytic purposes, sensing or adsorption processes.…”

Layered Double Hydroxides Containing an Ionic Liquid: Ionic Conductivity and Use in Composite Anion Exchange Membranes

Zinc-aluminum layered double hydroxide (LDH) containing an ionic liquid, 1-butyl-3-methylimidazolium hydrogen sulfate (BmimSO 4 ), has been synthesized by a co-precipitation method. This strategy enabled the intercalation of the ionic liquid (IL) into the interlamellar space of LDH with the aim of increasing the ionic conductivity and reducing its dependence on water content. Pure and IL-intercalated LDHs have been characterized by Fourier-Transform Infrared (FTIR) spectroscopy and X-ray diffraction. Electrochemical Impedance Spectroscopy (EIS) measurements showed that the addition of IL enhanced the ionic conductivity of LDH by a factor of 15 at low humidity and by a factor of 9 at high humidity conditions. As a possible application, LDHs were dispersed as a guest filler in a composite anion exchange membrane (AEM) based on polysulfone-DABCO. In this case, the addition of IL remarkably improved the ionic conductivity of the membrane from 1.0 · 10 À9 to 2.4 · 10 À7 S/ cm at low humidity. At high humidity, the membranes reached a conductivity of 25 mS/cm at 25 8C in OH form. Stability tests of composite AEM confirmed the positive effect of LDH nanoparticles. Figure 1. Chemical formulas of a) LDH and b) 1-Butyl-3-methylimidazolium hydrogen sulfate (BmimSO 4 ).

“…Also, for biosensing purpose, cellulase was immobilized on MgAlLDH [51]. Hemoglobin (Hb), which is an ironcontaining protein, was immobilized on exfoliated CoAlLDH [52] and ZnAlLDH [53]. Both Hb-LDH biosensors were used successfully for trichloroacetic acid biosensing, with high sensitivity and low detection limit.…”

Layered double hydroxides are known for over 150 years. The first discovered natural mineral with this structure was hydrotalcite [5], reported by Hochstetter in 1842, synthesized 100 years later by Feitknecht [6]. The structure of this compound is related to that of brucite in which part of Mg 2+ cations are replaced by Al3+. Carbonate anions are intercalated between the layers to maintain the electroneutrality of material. The presence of hydrotalcite in nature is reduced. For this reason, the synthesis of LDHs was
