“…There are various methods for the synthesis of LDHs, among which can be mentioned ion exchange, hydrothermal and co-precipitation methods. LDHs are neutral materials, the middle parts of the anion and the layers themselves have a positive charge, which have many applications in different fields due to their easy synthesis and the ability to replace and modify the hydroxide layers, which have attracted a lot of attention from researchers, such as adsorbents 7 , catalyst bases 8 , 9 , anion exchangers, water electrolysis 10 , energy storage 11 , 12 , sensors. The easy separation of heterogeneous catalysts such as bilayer hydroxides provides an easy and fast route for catalyst recovery, and catalyst recovery is valid both green chemistry and economically.…”

A new heterogeneous nanocatalyst LDH@3-chloropyltrimethoxysilane@1,3-benzenedisulfonyl amine@Cu (LDH@TRMS@BDSA@Cu) was synthesized and confirmed by analyzes such as Fourier transform infrared spectroscopy, Field Emission Scanning Electron Microscopy, energy scattered X-ray spectroscopy (EDX), elemental mapping, X-ray diffraction analysis, heat gravity/heat derivatization (TGA) and differential scanning calorimetry. The newly synthesized nanocatalyst effectively catalyzed the reaction between different aryl aldehydes, malononitrile, different acetophenones and ammonium acetate in solvent-free conditions and they were converted into 2-amino-3-cyanopyridine derivatives with high efficiency. The reaction showed advantages such as simplicity, high stability, environmental friendliness, excellent efficiency and short time. Also, this catalyst is recyclable and was recycled 4 times without losing significant catalytic power.

“…Layered double hydroxides (LDH), also known as called hydrotalcite-like compounds, consist of a positively charged layer of metallic hydroxide and exchangeable anions ([M 1– x 2+ M 3+ x (OH) 2 ] (A n – ) x / n · m H 2 O). − LDH has a layered structure and M 2+ and M 3+ are distributed in the hydroxide layer in a highly neat way. Earlier studies on LDH-based materials have mainly used LDH characteristics to design structures and generate special morphologies.…”

Owing to the creation of a large number of surface active sites, surface modification is an efficient strategy for improving the catalytic performances of photocatalysts. Herein, zero-dimensional (0D) p-type NiS species were developed in situ on the large surface of NiAl-LDH by controlled vulcanization. Importantly, the development of the 0D p-type NiS species not only enriched the active sites but also triggered the in situ formation of a NiS/NiAl-LDH p−n heterojunction due to NiAl-LDH, which was utterly underdeveloped in the vulcanization modification procedure. This undoubtedly accelerated the faster separation and migration of charge carriers and yielded improved photocatalytic hydrogen evolution. The optimum hydrogen production rate of the NiS/NiAl-LDH photocatalyst could reach 3408 μmol•g −1 •h −1 using a 5 W LED simulation visible light, which was 52-fold that of NiAl-LDH. The design and construction of the in situ p−n heterojunction may provide a perspective for the formation of p−n heterojunction photocatalysts with a closer contact interface and highly enhanced photocatalytic activity.

“…The morphologies of LDHs are generally two-dimensional sheets 17 or flowers. 18 At the same time, LDHs show a variety of core–shell structures, 19,20 hollow structures, 21,22 heterostructures, 23,24 etc . Different morphologies and structures lead to a large specific surface area and rich active sites on the surface of LDH materials, which provides LDHs great applications in adsorption, 25–27 electrochemical conversion 28–30 and energy storage.…”
