A Solution Chemistry Approach for the Selective Formation of Ultralong Nanowire Bundles of Crystalline Cd(OH)2 on Substrates

The controlled precipitation of a supersaturated Cd2+ solution is used to selectively deposit Cd(OH)2 nanowire bundles on a substrate. As schematically depicted in the figure, when the Cd2+ ionic product exceeds the solubility product, heterogeneous and homogeneous nucleation occur independently on...

Zusammenfassung:The controlled precipitation of a supersaturated Cd2+ solution is used to selectively deposit Cd(OH)2 nanowire bundles on a substrate. As schematically depicted in the figure, when the Cd2+ ionic product exceeds the solubility product, heterogeneous and homogeneous nucleation occur independently on the substrate and in the solution to give nanowire bundles and hexagonal plates, respectively.
