The present invention relates to a method for preparing doped anionic clay,n n n In this method, a trivalent metal source is reacted with a divalent metal source to obtain a doped anionic clay, wherein at least one of the metal sources is doped boehmite, doped MgO or doped hydrocalcite. Suitable dopants include alkaline earth metals (eg Ca and Ba), alkali metals, transition metals (eg Co, Mn, Fe, Ti, Zr, Cu, Ni, Zn, Mo, W, V, Sn), It is characterized in that the compound containing an element selected from the group consisting of actinium element, rare earth metals (eg La, Ce and Nd), precious metals (eg Pt and Pd), silicon, gallium, boron, titanium and phosphorus. |
