Effect of synthesis method on properties of layered double hydroxides containing Ni(III)

Abstract

Unstable oxidation state +3 of nickel can be stabilized in the structure of layered double hydroxides, the resulting crystallinity and properties being dependent on the synthesis method. Three different wet chemical methods (co-precipitation at variable pH, co-precipitation followed by hydrothermal treatment, co-precipitation with icrowave treatment) were used to synthesize Mg/Ni-Al layered double hydroxides containing triply charged nickel cations
