The syntheses of Mg-Fe(III) layered double hydroxides with different compositions at varied temperature through a co-precipitation method were attempted. The well -crystallized and white colored layered double hydroxides with chloride anions were obtained from the samples adjusted to the composition of Mg/Fe = 4 and aged at higher temperature. The Fe species in the white colored Mg-Fe layered double hydroxides were evaluated as all Fe(III) species by a Mossbauer measurement. The synthesized Mg-Fe(III) layered double hydroxide was treated with a sugar alcohol at temperature above its melting point in order to reduce Fe(III) incorporated into the hydroxide layers. The Mg -Fe layered double hydroxide resulting from a sugar alcohol treatment showed the reduction property in an aqueous solution. (C) 2015 Elsevier B.V. All rights reserved.
