Observation of staging during intercalation in layered alpha-cobalt hydroxides: a synthetic and kinetic study.
The anion-exchange reaction of the layered alpha-cobalt hydroxides Co(OH)(1.75)(DDS)(0.25).0.6H(2)O (1) and Co(OH)(1.7)Cl(0.3).0.4H(2)O (3) with carbonate has been investigated. For 3 the reaction proceeds by complete displacement of the interlayer Cl(-) anions by CO(3)(2-) to give Co(OH)(1.7)(CO(3))(0.15).0.6H(2)O (4). Remarkably for 1 we only observe ion-exchange of the DDS(-) from every other layer to give the second stage intercalate Co(OH)(1.75)(DDS)(0.07)(CO(3))(0.09).0.5H(2)O (2). The ...Expand abstract
