Lanthanide-doped layered double hydroxides and method of producing same Universiteit Antwerpen
The present invention relates to a method for producing lanthanide doped layered double hydroxides (Ln-doped LDHs), said method comprising the steps of preparing a carbonate free alkaline solution; preparing a solution of metal salts comprising a salt of a lanthanide; co-precipitating the alkaline solution and the solution of metal salts to form a mixture and Ln-doped LDH precipitate wherein the pH of the mixture is maintained at a constant value; aging the precipitate; and separating the precipitate from the solution. The alkaline solution is an aqueous ammonia solution. The invention is ...
