METHOD OF PRODUCING INORGANIC LAYERED DOUBLE HYDROXIDES, NOVEL INORGANIC LAYERED DOUBLE HYDROXIDES AND USES OF THE SAME

摘要

Novel nanosized layered double hydroxide materials and a method of producing the same as well as uses of said material. The novel materials are uniform and have the general formula (I) [M²⁺_1-xM³⁺ _x(OH)₂] [A^n-_x/n ·zH₂O] wherein M²⁺ is selected from Mg^2+, , Ca²⁺, Mn²⁺, Fe²⁺, Co²⁺, Ni²⁺, and Zn²⁺ M³⁺ is selected from Al³⁺, V³⁺, Cr³⁺, Fe³⁺, Co³⁺,Sc³⁺, Ga³⁺, and Y³⁺, A^n-stands for an anion, x stands for a value in the range from 0.2 to 0.33, n is an integer from 1 to 4 and z is an integer from 1 to 10. 1 The particle size is less than 1 μm. The material can be used in heterogeneous catalysis in organic chemistry and petrochemistry, magnetic materials, pharmaceutical applications, electrode materials, tissue engineering, cosmetics,and dietary supplements.
