“…Hydrotalcites are also applicable for NO x removal from exhausted gases, for which their layered structures and flexible physicochemical properties grant them good selectivity for NO x elimination. For such reactions, several chemical compositions have been developed based on hydrotalcite structure, which can be found in cited references [110][111][112] . Co-containing Mg-Al hydrotalcite has exhibited remarkable efficiency for NO x removal after calcination at higher temperatures (e.g., 700 °C) because of the formation of spinel phases.…”

Hydrotalcites are inorganic layered materials which have been used in a wide spectrum of applications from catalysis and adsorption to heavy metals immobilization and polymer stabilization. Apart from this, they can act as drug carriers or acid scavengers. More recently, due to the urgent need for developing functional materials required in the production of renewable fuels and chemicals, hydrotalcites have been increasingly noticed as versatile compounds. For instance, they are applicable in biofuel synthesis, biomass upgrading, plastics degradation, hydrogen storage and so forth. In addition, they are cost-efficient materials and thus beneficial for the realization of the above-mentioned applications on the industrial scale. It is noteworthy that for further development of novel hydrotalcites, validation of their performance and their stability are essential. To elucidate these aspects, the major significance of these materials and their capability for application in various catalytic fields are discussed in this survey. Particular focus is given to their most recent utilization in sustainable and green applications.

Hollow @CuMgAl double layered hydrotalcites and mixed oxides with tunable textural and structural properties, and thus enhanced NH₃-NO_x-SCR activity

Abstract: Well-organized, spherical, mesoporous hollow @CuMgAl-LDHs (layered double hydroxides) are prepared by the controlled removal of the SiO2 from SiO2@CuMgAl-LDH core–shell hybrids that in turn are synthesized via a bottom-up strategy.
