Abstract
What is provided is a layered double hydroxide crystal for achieving higher ion-exchange capacity than that of the related art. The layered double hydroxide crystal 1 according to the present embodiment is represented by Formula (1) and composed of a plurality of crystal grains 10 each of which has a lamination structure in which a plurality of plate-shaped crystals (11), (11), . . . are laminated, in which particle sizes of the plurality of crystal grains (10), (10), . . . are uniform on a microscale. [Ni2+1−xFe3+x(OH)2]·[(Cl−)X/2] (1) (Where, 0.25<x≤0.9)
Claims5
A layered double hydroxide crystal represented by Formula (1) comprising:
