We demonstrated that analyzing the formed gels containing exfoliated nitrate or glycine intercalated layered double hydroxide (LDH) nanosheets in formamide using X-ray diffraction is a simple and reliable method for determining the delamination degree of LDHs in formamide, which shows many advantages compared to the common characterization technologies.

Fabricating active materials into specific macrostructures is critical in the pursuit of high electro-catalytic activity. Herein we demonstrate that a three-dimensional (3D) architecture of NiFe layered double hydroxide (NiFe-LDH) significantly reduced the onset potential, yielded high current density at small overpotentials, and showed outstanding stability in electrochemical oxygen evolution ...

MgAl-Layered double hydroxide (LDH) films with different orientations on the two sides of a glass substrate, one of which was modified with poly(vinyl alcohol), have been obtained by a one-step in situ hydrothermal crystallization method, and the growth mechanisms of the two films are discussed.

By controlling the ratio of tri- and bi-valent ions, multi-transition metal based layered double hydroxide (LDH) ultrathin nanosheets are synthesized. They show advanced OER performance with low overpotentials (∼0.2 V) and decreased Tafel slopes with increasing Co incorporation due to the modulated electronic structures of catalytic centers and the increased surface area and electronic conducti...

Mg-Al layered double hydroxide (LDH) nanocrystallites with a lateral size less than 9 nm were in situ synthesized within the pore channels of mesoporous silica materials, creating one of the most active heterogeneous base catalysts owing to the high number of active edge sites.

CoAl-layered double hydroxide nanosheets (CoAl-NSs) could serve as an active matrix to effectively anchor amorphous MoSx nanoparticles with high dispersion and the formation of an additional active "CoMoS" phase. The resulting CoAl-NSs/MoSx catalyst showed 13 times higher H2 evolution activity than free MoSx nanoparticles from an erythrosin B-triethanolamine (ErB-TEOA) system under visible light.

CoO/CoFe(2)O(4) nanocomposites, derived from scalably prepared CoFe-layered double hydroxide (CoFe-LDH) single-resource precursors, exhibit tunable cycle performances and rate capabilities, which are supported by the homogenous dispersion of bi-component active CoO and CoFe(2)O(4) phases.

The present communication demonstrates the proof of concept of using CoFe layered double hydroxide (CoFe-LDHs) nanoplates as an effective peroxidase mimetic to catalyze the oxidation of peroxidase substrate 3,3',5,5'-tetramethylbenzidine in the presence of H(2)O(2) to produce a blue solution. We further demonstrate successfully CoFe-LDHs nanoplate-based colorimetric assay to detect H(2)O(2) and...

We fabricated two-color luminescence ultrathin films (UTFs) composed of the layered double hydroxide host-aggregation-induced emission guests by LBL assembly. The fabricated UTFs were simple, tunable, controllable and highly luminescent. Moreover, reversible thermochromic luminescence further exhibited their potential in practical applications.
