“…LDH have been studied extensively for a wide range of applications utilizing catalysts [1,8,9], ceramic precursors [10] adsorbents [11], bio-organic nanohybrids [12,13], and scavengers of pollutant metals and anions [14]. Recent research has shown great flexibility of the LDH-like materials in tailoring chemical and physical properties of materials to be used for specific applications, e. g. molecular recognition, optical storage, batteries, ..etc [15][16][17].…”

These preliminary results open up a new direction towards the synthesis of nanocomposites using polymeric entities and layered materials for future applications in cement and concrete science, e.g. control of the effect of admixtures on the kinetics of cement hydration by programming their temporal release.

“…LDHs have a wide range of applications in many fields, e.g., as catalysts or catalyst precursors, ion exchangers, adsorbents for environmental contaminants, and substrates for the immobilization of biological material [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Thermal decomposition of the LDH at high temperature leads to the formation of mixed metal oxide (MMO) materials composed of spinel-like (M Ⅱ M Ⅲ 2 O 4 ) phases and other metal oxide phases (M Ⅱ O) and previous studies have shown that such materials can be used as catalysts and catalyst supports, sensors, and Li-ion battery electrodes [15][16][17].…”

NiFe 2 O 4 nanoparticles (<10 nm) embedded in a NiO matrix have been fabricated by calcining the corresponding Ni Ⅱ Fe Ⅲ -layered double hydroxide (LDH) precursors at high temperature (500 °C ). Compared with the NiFe 2 O 4 /NiO nanocomposite obtained by calcination of a precursor prepared by a traditional chemical coprecipitation method, those derived from NiFe-LDH precursors show much higher blocking temperatures (T B ) (~380 K). The enhanced magnetic stability can be ascribed to the much stronger interfacial interaction between NiFe 2 O 4 and NiO phases due to the topotactic nature of the transformation of the LDH precursor to the NiFe 2 O 4 /NiO composite material. Through tuning the Ni Ⅱ /Fe Ⅲ molar ratio of the NiFe-LDH precursor, the NiFe 2 O 4 concentration can be precisely controlled, and the T B value as well as the magnetic properties of the final material can also be regulated. This work represents a successful example of the fabrication of ferro(ferri)magnetic (FM)/antiferrimagnetic (AFM) systems with high magnetic stability from LDH precursors. This method is general and may be readily extended to other FM/AFM systems due to the wide range of available LDH precursors.

“…In the above formula, typically 0.2 e x e 0.33, but LDH with significantly higher x values have also been reported. 4 The most frequently studied LDH is [Mg 1-x Since these materials have a well-defined layered structure with nanometer (0.3-3 nm) interlayer distances and contain important functional groups, they are widely investigated for use as adsorbents for liquid ions [5][6][7] and gas molecules 8,9 and as catalysts for oxidation, [10][11][12] reduction, 13 and other catalytic reactions. [14][15][16] Recently, LDH materials have also been investigated in novel reactive separation processes to increase the conversion of catalytic reactions by removing one of the products from the reactor.…”

In our prior study, we employed several in-situ techniques to investigate the thermal evolution of the structure of a Mg-Al-CO 3 layered double hydroxide (LDH) under an inert atmosphere and proposed a model to describe the structural evolution of the Mg-Al-CO 3 LDH structure. In this paper we present results of our ongoing investigations with these materials pertaining to their sorption characteristics and thermal reversibility under both inert and reactive atmospheres. The experimental observations are shown to be consistent with the structural model for the LDH previously proposed. The structure, sorption characteristics, and thermal reversibility of these materials are of importance in their use for the preparation of CO 2 -permselective membranes for high-temperature membrane reactor applications.
