Abstract:
1. A preparation method for preparing an anion-exchangeable, layered double hydroxide, comprising: dispersing a starting material in an aqueous solution mixed with a salt containing minus monovalent anions (X wherein the starting material is a carbonate ion type layered double hydroxide (LDH) having a composition represented by a general formula: Q where x is indicative of a numeral range of 1.8≦x≦4.2, z is indicative of 2(x+1), y is indicative of a minimum value of at least 0 that increases to less than 1 when anions (X Q is a divalent metal ion, R is a trivalent metal ion, and n is 2±2, and y in said general formula increases to a maximum of 1 by substitution of the minus monovalent anion (X
