Feb 21, 2018 · A comprehensive nanoscale understanding of layered double hydroxide (LDH) thermal evolution is critical for their current and future applications as catalysts, flame retardants and oxygen ...

May 20, 2020 · We provide the first direct atomic-scale evidence that, under applied anodic potentials, MFe LDHs oxidize from as-prepared α-phases to activated γ-phases. The OER-active γ-phases are characterized...

Jan 30, 2001 · We have now determined the crystal structures of two isoforms of human LDH-the M form, predominantly found in muscle; and the H form, found mainly in cardiac muscle. Both structures have been crystallized as ternary complexes in the presence of the NADH cofactor and oxamate, a substrate-like inhibitor.

Dec 1, 2023 · We examine the structure and properties of LDHs materials, including aspects such as tunability, structural memory effect, thermal stability, acidity and alkalinity, stripability and assemblability. Various synthesis methods for LDHs materials are described, encompassing coprecipitation, urea hydrolysis, hydrothermal, sol-gel, and template.

In this report, we present an analytical method to characterize the crystal structure of LDHs using Rietveld refinement, XPS, and XANES. Using this analytical method, we found that ZnCo LDH nanoplates prepared by a new facile synthetic route had a Zn 3.1 Co 1.9 Cl 2 (OH) 8 ·H 2 O structure and contained a large portion of divalent Co cations ...

Layered double hydroxides (LDHs), a class of anionic clays consisting of brucite-like host layers and interlayer anions, have been widely investigated in the last decade due to their...

4 days ago · The structural and morphological analysis of Ni-LDH was conducted using techniques such as XRD, SEM, FTIR, and Raman spectroscopy to determine its crystallographic structure, surface morphology ...

Jan 1, 2011 · The structures of all studied LDH crystals consists of metal hydroxide layers, [Mg 2 Al (OH) 6] +, and disordered interlayer (Fig. 7 a). According to LDH polytype nomenclature (see above), the layer stacking in quintinite-2 H -3 c can be described as …

6 days ago · In this paper, a built-in electric field (BEF) strategy is proposed to fabricate NiFe-LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen ...

Layered double hydroxides (LDHs) are lamellar compounds having molecular formula [M (II) 1−x M (III) x (OH) 2] x+ (A n−x/n)·mH 2 O, where x ranges from 0.22 to 0.33, M is a metal and A n− is a n− valent anion.
