“…A number of works address the role of the catalyst preparation method and the nature of the oxide precursor [15,19,20,30,31,33,[40][41][42][43]. In particular, the use of precursors related to the naturally occurring mineral known under the name of hydrotalcite has been indicated as providing particularly active mixed oxide catalysts [24,27,34,35,39,45,46]. Natural hydrotalcite is a layered magnesium aluminium hydroxy carbonate, but the structure can accommodate a number of other cations, in a broad range of ionic radii [48].…”

“…In different redox reaction (e.g. : selective oxidation of hydrocarbons or the total oxidation of VOCs [65]) mixed oxides, obtained after the calcination phase, have been able to act as catalysts [59,62], or as catalyst support [63][64][65].…”

“…The wide range of possible cations and anions that can be incorporated in the structure gives rise to a large number of catalytic materials [59,60]. Mixed oxides have been shown to be very active and selective in the decomposition of NOx [61] or in total oxidation of VOCs [62][63][64]. In different redox reaction (e.g.…”

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.

“…For example, mixed oxides have been shown to be very active and selective in the decomposition of nitrogen oxides [16] or in the total oxidation of Volatile Organic Compounds [13,14]. Also, mixed oxides obtained after calcination were used equally as catalysts [13,17] or as catalytic support [18][19][20] in redox reactions such as the selective oxidation of hydrocarbons or the total oxidation of VOCs [21,22].…”

Co6Al2HT hydrotalcite-like compounds were synthesized by three different methods: co-precipitation, microwaves-assisted and ultrasound-assisted methods. The mixed oxides obtained after calcination were studied by several techniques: XRD, TEM, H2-TPR and XPS. They were also tested as catalysts in the reaction of total oxidation of toluene. The physico-chemical studies revealed a modification of the structural characteristics (surface area, morphology) as well as of the reducibility of the formed mixed oxides. The solid prepared by microwaves-assisted synthesis was the most active. Furthermore, a relationship between the ratio of Co 2+ on the surface, the reducibility of the Co-Al mixed oxide and the T50 in toluene oxidation was demonstrated. This suggests a Mars Van Krevelen mechanism for toluene total oxidation on these catalysts.
