The development of new or modified cementitious materials is an important part of existing strategies to improve performance and minimize life-cycle costs and to eliminate the CO2’s impact on durability. The high anion exchange capacity of layered double hydroxides (LDHs) materials makes their interlayer ion exchange by organic and inorganic anions versatile and easily achieved. LDH-like materi...

Abstract Layered double hydroxides as typical supercapacitor electrode materials can exhibit superior energy storage performance if their structures are well regulated. In this work, a simple one-step hydrothermal method is used to prepare diverse nickel–cobalt layered (NiCo-LDHs), in which the different contents of urea regulate nanostructures NiCo-LDHs. The results show that decrease content ...

The performance profile of a supported metallocene catalyst in slurry-phase ethylene polymerisation can be significantly enhanced by tuning the chemical composition support. By employing supports derived from zinc-containing layered double hydroxides (LDHs), slurry phase productivity (EBI)ZrCl2 (EBI = rac-ethylenebis(indenyl)) quadrupled relative to magnesium-containing Productivity increases a...

Abstract Layered double hydroxides (LDHs) of various compositions, i.e. Mg–Al, Mg–Mn–Al, are applied as the precursors metal oxides for preparation N-doped carbon materials via chemical vapour deposition (CVD) with acetonitrile (as and nitrogen source) at 600 700 °C. The use Mn-containing LDHs is a novelty. impact transition species, Mn x O y , in blend derived from on amount deposit its compos...

This paper reports a number of recent developments in the intercalation chemistry of Al(OH)(3). From Rietveld refinement and solid-state NMR, it has been possible to develop a structural model for the recently reported [M(II)Al(4)(OH)(12)](NO(3))(2)·yH(2)O family of layered double hydroxides (LDHs). The M(2+) cations occupy half of the octahedral holes in the Al(OH)(3) layers, and it is thought...

Abstract Electron irradiation of Ni–Fe layered double hydroxides (LDHs) was investigated in the transmission electron microscope (TEM). The initial structure possessed a flat hexagonal morphology made up crystalline domains with well-defined crystal structure. LDHs were susceptible to significant structural decompositions during irradiation. generation pores and crystallographic breakdown LDH r...

Millions of people worldwide are exposed to excessive concentrations fluoride (F−) from groundwater sources. Ca-Al-CO3 layered double hydroxides (LDHs) have shown promising defluoridation efficiency; however, by LDHs is highly pH sensitive. This study showed that simultaneous acidification conventional acids, such as HCl and CO2 substantially increased the performance for F- removal at environm...

Differential scanning calorimeter was used to extensively investigate the non-isothermal crystallization of polypropylene (PP)/layered double hydroxides (LDHs) nanocomposites prepared through wet solid-state shear milling. The corresponding crystallization kinetics was further investigated by using Ozawa, modified Avrami and combined Avrami-Ozawa method, respectively. The results showed that th...

This work focuses on the synergetic effect obtained by immobilization of Rhamnus frangula L. (RfL) phytoextract in layered double hydroxides (LDHs) matrixes and their subsequent encapsulation into biocompatible hydrogels (HG). In this respect, LDHs were used as hosts for a reconstruction method, after which LDHsRfL embedded hydrogel (HG) matrixes, based polyethylene glycol diacrylate (PEGDA), r...

Layered double hydroxides (LDHs) have been reported as one of the most effective materials for oxygen evolution reaction (OER) catalysts, which are prone to hydrolysis and oxidation under OER conditions. Metal–organic frameworks (MOFs) porous with high crystallinity internal surface area. The design LDHs based on MOFs has attracted increasing attention owing their area, exposed catalysis sites,...
