“…It is still a one-step recipe that guarantees quite a good adhesion and morphology [30][31][32]. Instead of adopting dissolved metal salts, one of the two metals is provided as a substrate, which behaves either as a sacrificing element for the film growing on it, or a reacting source of one of the corresponding metal.…”

The peculiar properties of layered Double Hydroxides (LDH) have progressively drawn the attention of the scientific community. The main characteristic of LDH is the ability to capture anionic species (organic and inorganic) to build different composites. This is made possible by the sandwich structure of the LDH, similar to the brucite architecture, made up of positive charged lamellas interspersed by anions. Several distant fields, ranging from medicine to physics and engineering, exhibit interest in LDH applications. To satisfy all those requirements, energy was spent to sculpt LDHs physical and chemical properties and for designing layered double hydroxides "ad hoc" for different needs and employments. Notably, among the many applications, those related to metallurgical processes and products are of particular interest. This paper presents the characteristics, the main preparation routes and reviews the applications of LDH to metallurgy with some examples taken from the experimental research of the author.

Abstract:The inexpensive and green method of synthesis for self-assembled micro/nano structures is an important area of emerging research. Such structures can be chemically tuned with predesigned functional properties. Therefore, they hold very good promise for future applications, e.g., biomedicine, electronic device, solar energy, gas sensing. Here we report for the first time an inexpensive and green method for chemical deposition of magnesium hydroxide (Mg(OH) 2 ) micro/nano flowers in thin films on commercial soda lime silica glass substrates at room temperature. Under identical conditions, chemically synthesized Mg(OH) 2 powders are also prepared in absence of the soda lime silica glass substrates. The condition that favors the growth of micro/nano flowers in thin films is identified from X-ray diffraction (XRD), scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDX) data. Finally, the possible growth mechanism of micro/nano flowers in thin films is discussed.

“…Anionic clays as another kind of important catalyst minerals are widely used in the fields such as base catalysis, hydrogenation, polymerization, condensation, alcohol transformation, which show high catalytic activity and good chemoselectivity [91][92][93][94]. Anionic clays are also named as "layered double hydroxides" or simply "hydrotalcites", which can be generically formulated as…”

Baeyer-Villiger (BV) oxidation is one of the most important transformation reactions in synthetic organic chemistry. Catalytic versions of the BV oxidation are particularly attractive in practical applications, because the catalytic transformation substantially simplifies reaction process while minimizing reactant consumption as well as waste production. Further benefits are expected from replacing peracids, the traditionally used oxidant, by low cost and environmentally friendly hydrogen peroxide (H2O2). This review will first introduce very briefly the features of BV oxidation reactions, and the corresponding oxidants traditionally used. Afterwards, the emphasis will be placed on the specific Sn-based catalysts, their performance comparison for the BV oxidation reaction by using H2O2 as oxidant, and the catalytic mechanisms of most Sn-based catalysts reported so far, including homogeneous Sn-based catalysts (such as Sn-based fluorous biphase system catalysts), heterogeneous Sn-based catalysts (such as Sn-based zeolite catalysts, Sn-based mesoporous composites, Sn-incorporated clay catalysts, Sn-based metal oxide composites and polymer supported Sn catalysts). Finally, the Sn-based catalysts for BV oxidation are outlooked for their potentials and perspectives in enhancing the performance and then accelerating the practical applications of BV oxidations by using H2O2. The developing direction of the Sn-based catalytic BV reaction is also illustrated.
