Surfactant intercalated α-hydroxides of cobalt and nickel and their delamination-restacking behavior in organic media

Dodecyl sulfate and dodecylbenzene sulfonate intercalated α-hydroxides of nickel and cobalt were synthesized by ammonia precipitation. These solids delaminate to give a colloidal dispersion of layers in organic solvents such as 1-butanol. The dispersed layers could be reassembled either by evaporation of the colloid or by coagulation by the addition of a polar solvent.
