Beschreibung
Zusammenfassung:	The present invention relates to a method for producing lanthanide doped layered double hydroxides (Ln-doped LDHs), said method comprising the steps of preparing an alkaline solution, wherein the alkaline solution does not comprise carbonates; preparing a solution of metal salts comprising a salt of a lanthanide; combining the alkaline solution and the solution of metal salts so as to form a mixture of Ln-doped LDH precipitate and solution thereby maintaining the pH of the formed solution at a constant value; aging the precipitate; and separating the precipitate from the solution. The invention is also related to lanthanum-doped layered double hydroxides (La-doped LDHs) obtainable by such a method, as well as to the use of the lanthanide-doped layered double hydroxides obtainable by such a method.
