Lamellar double hydroxides

In recent decades clays have been widely used as an integral part of industrial processes mainly due to the low cost of these materials as well as their sustainable potential as they are materials that can be regenerated and reused in successive processes. Natural anionic clays are relatively rare materials compared to cationic clays but their good and easy reproducibility in the laboratory and simple regeneration after use make these materials very accessible for industrial applications especially in terms of their cost-benefit ratio.
